[oweals/busybox.git] / Changelog

0.47

        * A bug in syslogd was fixed that allowed it to potentially fork-bomb
            your system.
        * Renamed busybox.defs.h to the more sensible "Config.h"
        * Improved portability between different libcs.
        * Many apps ported to use getopt()
        * Common handling of '--help'
        * All usage messages centralized.
        * Added a bunch of new commands:
            * 'rdate' contributed by Sterling Huxley <sterling@europa.com>
            * 'wget' contributed by Chip Rosenthal <chip@unicom.com>, 
                    <crosenth@covad.com> and Covad Communications
            * 'getopt' from "Alfred M. Szmidt" <ams@trillian.itslinux.org>
            * dos2unix, unix2dos, reset, and unrpm.c (and lots of help
                debugging) thanks to Kent Robotti <robotti@metconnect.com>.
            * 'renice' command, thanks to Dave Cinege <dcinege@psychosis.com>
            * 'xargs' (written by me)
            * 'expr' contributed by Edward Betts <edward@debian.org>, based
                on GNY expr
        * lsmod now uses the query_module syscall, rather then /proc (me)
        * syslogd can now log messages to remote hosts -- patch thanks
            to Gyepi Sam <gyepi@praxis-sw.com>
        * chroot can now call the builtin shell - Pavel Roskin <proski@gnu.org>
        * 'make install' now creates relative symlinks, and added a new
            'make install-hardlinks' target to (tada) install hardlinks.
        * Rewrite of 'tail' to make it simpler, smaller, and more robust.  
            It now weighs only 2.25k (3k when full featured).  The code is
            cleaner too, thanks to Allen Soard <esp-software@mail.hypermart.net>
        * Add optional ls file sorting, thanks to a patch from 
            Sterling Huxley <sterling@europa.com>
        * Fixed chmod option parsing so things like 'chmod -r /tmp/file'
            now work (previously it thought -r was an option).  Doh!
        * Fixed tar handling of stdin and stdout
        * Renamed "internal.h" to the more sensible "busybox.h"
        * Preliminary support for GNU HURD.
        * Tons of other bugfixes.

0.46

        * Better portability.  Now should compile cleanly with libc5, 
            GNU libc 2.0 and 2.1, and various Linux kernels including 
            2.0.x, 2.2.x, and to 2.4.0-test*. (patch for 2.4.x kernels
            to make /proc/mounts behave included in the kernel-patches dir). 
        * Fixed a _horrible_ bug where 'tar -tvf' could unlink
            local files that matched tarball contents!!!  Fix thanks 
            to Marius Groeger <mgroeger@sysgo.de>
        * Fixed a nasty bug in tar when could mess up saved symlinks.
        * Fixed tar creation support when reading from stdin ('tar -cf - . ') 
            thanks to Daniel Quinlan <quinlan@transmeta.com>
        * Updates to handle Linux 2.4.0 kernels (kludged around the
            "none" entries in /proc/mounts, added a hack to make sysinfo
            work with both old and new kernels).
        * Fixed insmod module option parsing for options lacking an '='.
            Fix thanks to Marc Nijdam <marc_nijdam@hp.com>
        * Fixed segfault with 'cut -f 1 -d:' and added 'cut -s' suport.
            Fix thanks to Arne Bernin <arne@matrix.loopback.org>
        * Several fixes from Marius Groeger <mag@sysgo.de>
            - Added support for "sh -c command args..."
            - Fixed globbing, i.e. 'echo * *' and 'echo "******"' now work.
            - Added shell environment variable substitution 
            - Added the "read" shell builtin.
        * Fixed cursor editing in cmdedit.c. The following keyboard sequence 
            used to create an infinite loop: ls, cursor up, left, down.
        * Added support for being a login shell, so things like
            '-su' or '-sh' (stuff where argv[0][0]=='-') will now always 
            invoke the shell.  Now you can use BusyBox as a login shell.
        * ls.c now ignores '-g', since some ftp clients like that sort 
            of thing.  Patch thanks to David Vrabel <dvrabel@arcom.co.uk>
        * Fix to init.c from Stuart Menefy <Stuart.Menefy@st.com> so that
            it always sets the controlling terminal before running any programs
        * Several fixes from Matt Kraai <kraai@alumni.carnegiemellon.edu>
            - Fixed tr so it recognizes standard escape sequences.  
                Merged common escape seq. code from tr and echo into utility.c.
            - Major work in updating/cleaning up the docs, and getting the
                new SGML based docs into shape.
            - cleanup of ar.c
            - BusyBox should now poweroff when asked to do so.
            - Fixed 'ln -n' and 'ln -s' so they both work properly.
        * Reorganized signal names in kill.c for better architecture support 
            -- patch thanks to simon wood <simon@mungewell.uklinux.net>
        * In 0.43, backspace and delete worked properly, but with 0.45, 
            it just echoed a ^? for backspace, and ^H for control-h.  This
            was due to a broken macro in init.c, that is now fixed.
        * Removed sfdisk from BusyBox.  It was buggy, fat, and we really
            couldn't maintain it very well, so including it was not really
            very appropriate.  Those wanting an fdisk are invited to
            grab a copy from util-linux.
        * Added 'dumpkmap' to allow people to dump a binary keymap, which can 
            then be loaded in by 'loadkmap' -- submitted by
            Arne Bernin <arne@matrix.loopback.org>
        * Fixed NFS so it supports 2.4.x kernels and NFSv3.
        * Brand, new versions of grep and sed which use libc regex routines,
            thanks to Mark Whitley <markw@lineo.com>.  The hand-tooled 
            "regexp.[ch]" files have been removed. Much help on these from 
            Matt Kraai as well.


         -Erik Andersen


0.45
        * Now compiles vs libc5 (which can save lots of space for 
            embedded systems).
        * Added BB_FEATURE_TRIVIAL_HELP which compiles out most all of the
            help messages (i.e --help).  Saves 17k over a full compile.
        * Added cut and tr from minix, since due to the license change, 
            we can now use minix code.  Minix tr saves 4k. 
        * insmod now works.  It costs 29k, but imagine an initrd with a 
            staticly linked busybox containing only insmod and sh, a few /dev 
            entries, and a kernel module or two...  It doesn't get smaller
            then this folks (I pity the fool that writes insmod in asm ;-).
            Many kudos go to Ron Alder <alder@lineo.com> for finishing this off!
        * Added a mini ar archive utility, especially written for BusyBox by 
            Glenn McGrath <bug1@netconnect.com.au>
        * Added mktemp, contributed by Daniel Jacobowitz <dan@debian.org>
        * Added setkeycodes, for those that have wierd keyboard buttons.
        * Added md5sum, uuencode and uudecode -- thanks to Alfred M. Szmidt 
            <ams@trillian.itslinux.org> for contributing these.
        * Added 'grep -v' option (inverted search) and updated 
            docs accordingly.  -beppu
        * Wrote which
        * Replaced the telnet implementation with one written by 
            Tomi Ollila <too@iki.fi> It works great and costs 3k.
        * BusyBox sh (lash) now supports being used as a standalone shell.  When
            BB_FEATURE_SH_STANDALONE_SHELL is defined, all the busybox commands may
            be invoked as shell internals.  Best used when compiling staticly 
            (i.e. DOSTATIC=true)
        * BusyBox sh (lash) internals now behave as expected wrt pipes 
            and redirects. 
        * Fixed ping warnings -- fix from Sascha Ziemann <szi@aibon.ping.de>
        * Fixed update segfault
        * Fixed mknod -- minor number was always 0
        * Fixed tar option parsing, so both "tar xvf foo.tar" and 
            "tar -xvf foo.tar" now work (i.e. no "-" before options) 
            (this was very broken in 0.43).
        * Several contributions from Randolph Chung <tausq@debian.org>.
            * cp/mv now accepts the -f flag
            * tail can now accept -<num> commands (e.g. -10) for better 
                compatibility with the standard tail command
            * added a simple id implementation; doesn't support sup. groups yet
        * logname used getlogin(3) which uses utmp.  Now it doesn't. 
        * whoami used getpwuid(3) which uses libc NSS.  Now it behaves. 
        * Add support for "noatime" and "nodiratime" mount flags to mount.
        * Changed 'umount -f' to mean force, and actually use umount2.
        * Changed 'umount -l' to mean "Do not free loop device".
        * Fixed basename to support stripping of suffixes.  Patch thanks
            to xiong jianxin <jxiong@uiuc.edu>
        * cp -fa now works as expected for symlinks (it didn't before)
        * zcat now works (wasn't working since option parsing was broken)
        * Renamed "mnc" to the more correct "nc" (for netcat).
        * Makefile intelligence updates
        * Changed the way init parses /etc/inittab entries to avoid problems
            with commands that contain colons in them.  Fix thanks to 
            Pavel Roskin <proski@gnu.org>
        * Fixed a warning in utility.c due to char being unsigned on Linux/PPC, 
            Fix thanks to Pavel Roskin <proski@gnu.org>
        * Made "killall" complain (not error and exit) about processes that it 
            cannot find by name -- Pavel Roskin <proski@gnu.org> 
        * Fixed more and ps to have sensible terminal width defaults, thanks 
            to Pavel Roskin.
        * Fixed all fatalError() calls lacking a "\n", thanks to Pavel Roskin.
        * Fixed a segfault in yes when no args were given -- Pavel Roskin.
        * Simplified freeramdisk and added argument checking -- Pavel Roskin. 
        * Fixed segfault caused by "touch -c"
        * Fixed segfault caused by "rm -f"
        * Fixed segfault caused by "ln -s -s" and similar abuses. Further fixes
            and "--" support from Pavel Roskin.
        * Fixed segfault caused by "cp -a -a" and similar abuses.
        * Implemented "rm -- <foo>". Implementation fixed by Pavel Roskin.
        * "which" rewritten to use stat(). Fixes to improve its compatability
            with traditional implementations -- Pavel Roskin.
        * "mount" now reports errors from nfsmount() and assumes NFS mount
            if ':' is present in the device name - Pavel Roskin
        * Fixed exit status for killall - Pavel Roskin
        * Fixed 'swapon -a' and 'swapoff -a', which were broken.
        * Fixed 'mount -a' so it works as expected.
        * Implemented 'ls -R' (enabled by enabling BB_FEATURE_LS_RECURSIVE)
        * Implemented "ping -s", fixed error messages and argument parsing -
            Pavel Roskin
        * Syslogd will not go to background if "-n" is given. Better help
            and argument checking -- Pavel Roskin
        * Fixed a small bug that could cause tar to emit warning messages
            and not extract the first file in a directory in some cases
            of nested directories.  Thanks to Kevin Traas <kevin@netmaster.com>
            for helping track this one down.
        * More doc updates
        * Fixed grep "Line too long" problem -- John Beppu
        * Fixed 'grep -q -i B some_file' so it works
        * math takes input from stdin if no args are given.  -- John Beppu
        * math was renamed to dc.  Although it deviates from dc's behaviour,
            this will probably be remedied in the future.  -- John Beppu

0.44
        Previously, an erronous announcement of BusyBox 0.44 was made, so to 
        avoid possible confusion, we are skipping straight to 0.45, and calling
        it good.

         -Erik Andersen


0.43
        * Major update to the provided documentation.
        * Busybox now includes a shell!  It currently costs 7.5 k (plus an
            additional 2.5 k if you compile in command line editing).  Handles
            job control, has the usual set of builtins, and does everything
            except for handling programming statements (if, while, etc...)
        * Busybox can now work perfectly when /proc is disabled, thereby 
            saving a bunch of memory (kernel /proc support is not thin).  This
            is done by making use of some nice kernel patches I wrote up to
            support the features that busybox requires and that /proc usually
            provides.  To enable this, turn on BB_FEATURE_USE_DEVPS_PATCH and
            patch your kernel with the devps patch in the kernel-patches/
            directory. 
        * Wrote basename, dirname, killall, and uptime.
        * tar has been completely rewritten by me.  Both tar creation and 
            extraction are now well behaved.  Costs 7.6k with all optional
            tar features enabled, and 5k for just tar extraction support. 
        * Added freeramdisk, which will free up all memory associated
            with a ram disk.  Contributed by Emanuele Caratti <wiz@iol.it>
            and then adjusted a bit by me.
        * Added tr from John Lombardo <john@deltanet.com> 
        * Added echo and test (from me).
        * Added usleep contributed by Nicolas Pitre <nico@cam.org>
        * BusyBox's bss size has been majorly reduced (was 384668, is now 28740).
        * Several fixes from Pavel Roskin <proski@gnu.org>:
            - When `tail' fails to open a file it now exits.
            - When `syslogd' is given the `-n' option it should still use 
                fork() for running klogd.
        * nslookup types are now changed to u_int32_t (instead of uint32_t)
            changed per a patch from Pascal Bellard <pascal.bellard@ascend.com>
        * Fixed "du" so it gives the same answers as GNU "du" (busybox du used 
            to count hard-linked files more then once).  Many thanks to 
            Friedrich Vedder <fwv@myrtle.lahn.de> for the fix.
        * Removed /proc dependancies for init and free (while maintaining 
            exactly the same functionality).  /proc takes up 90k of kernel 
            space, so it is nice to avoid using it at all costs.
        * init no longer tries to mount /proc (unless there is less the 1 meg 
            free).  Use of /proc (or not) is policy that should be set up in 
            /etc/fstab (or in hardcoded scripts), not in init.
        * Fixed rebooting when init runs as an initrd.
        * Fixes and updates from Karl M. Hegbloom  <karlheg@debian.org>
            - update.c rewritten to look more like update-2.11
            - moveed the inode hash out of du.c and into utility.c to make 
                it a common resource that can be used by other apps.
            - cp_mv.c now checks inodes to see if a source and dest are
                the same, and prints an error (instead of endlessly looping).
            - mv now attempts to do a rename, and will fall back to doing
                a copy only if the rename fails.
            - Syslogd now supports multiple concurrent connections
        * Several fixes from Pavel Roskin <proski@gnu.org>:
            - Fixes to sort.  Removed "-g", fixed and added "-r"
            - Fixes to the makefile for handling "strip"
        * An initial telnet implementation was added by 
            Randolph Chung <tausq@debian.org>.
        * Fixed a bug where "sed 's/foo/bar/g'" (i.e. a script w/o a "-e")
        * ps now supports BB_FEATURE_AUTOWIDTH, and can adjust its width
            to match the terminal (defaults to width=79 when this is off).
        * ps now accepts (and ignores) all options except for "--help" (which
                as would be expected displays help).
        * Fixed mount'ing loop devices when the filesystem type was not 
            specified.  It used to revert to non-loop after the first try.
        * all mallocs now use xmalloc (and so are OOM error safe), and
            the common error handling saves a few bytes.  Thanks to 
            Bob Tinsley <bob@earthrise.demon.co.uk> for the patch.
        * Fix "+" parsing bug in date, from "Merle F. McClelland" <mfm@cts.com>.
        * Fix symlink following bug in chmod -R and friends.  
        * Now allows SYSV style 'chown foo:bar' in addition to 'chown foo.bar'
        * Fixed a bug in the busybox globbing routine such that 'find /dir -name [i]' 
            no longer segfaults.


        -Erik Andersen


0.42

        * Fairly massive restructuring of umount.c to deal with remounting 
          busy devices read-only. Adds a -r option to control that; it is 
          optionally compiled in with BB_FEATURE_REMOUNT
        * Added a bunch of functions to mtab.c to interact with the
          {get,set,end}mntent interface; as it turns out, those functions do
          not appear to be re-entrant, and that causes a lot of problems with
          the way umount was originally written.
        * Makes init send TERM and KILL (instead of HUP and KILL) on reboot
          to be more consistent with sysvinit
        * Changes to init.c to use the new -r option to umount. Also increased
          the sleep time between the time the TERM and KILL signals are sent

        - Randolph Chung


        * cp.c, mv.c: removed, replaced by cp_mv.c which has been
            extensively rewritten from the original cp.c.
        * Fixed cp and mv so if the source and destination are a the
            same directory it will print an error and continue.
        * Also added a warning message to the `mv' usage string saying that
            this is not GNU mv, and it will break hard links. cp also breaks
            hard links.
        * ln.c: implemented `-n' switch, no-deref symlinks.
        * include<sys/param.h>: and use PATH_MAX everywhere.  busybox: File
        * name buffer overrun guards to prevent future crashes.
            - Always check exit status.
            - Purge all use of `creat()', replace with `open()'.
        * utility.c 
            - recursiveAction was overriding the value of followLinks thus
              ignoring it.
            - isDirectory now takes a followLinks boolean, updated all callers
            - copyFile had the followLinks logic reversed.
        * messages.c: New file. Put common error message strings all in
            one place in an attempt to shrink the binary a little.

        -Karl M. Hegbloom


        * changed fsck_minix.c to reduce its .bss size significantly
          -beppu -piptigger
        * Made tar creation support in busybox tar optional.  You no longer
        * _have_ to put a "-" in front of tar options.  Tar could inadvertently
        * change permissions and ownership on
            certain directories pointed to by symlinks.
        * Made grep and grep -h do the right thing wrt printing
            the file name (it failed to print files names in many cases).
        * Fix a namespace aliasing problem wereby if du was built in, the 
            symlink for both du and dutmp would be installed, or then rm was
            built in, the symlinks for both rm and rmmod would be installed.
        * Added a closelog() to init.c after loging -- fix thanks to 
            Taketoshi Sano <kgh12351@nifty.ne.jp>
        * Rewrote and simplified logger.  Added the "-t" option, and made it
            behave itself a bit better.
        * Optional support contributed by Ben Collins <bcollins@debian.org> 
            for the kernel init chroot patch by Werner Almesberger, which
            allows init to chroot to a new device, and umount the old one.
        * Fixed bug that wouldn't let one chown a symlink -- it would
            always dereference before.  -beppu
        * Fixed a bug where init could have reference already freed memory.
            Found and fixed by Taketoshi Sano <kgh12351@nifty.ne.jp>
        * Several contributions from Friedrich Vedder <fwv@myrtle.lahn.de>
        * Added (and documented) "-n" option for head
        * Cleanup for a number of usage messages -- also 
            contributed Friedrich Vedder <fwv@myrtle.lahn.de>
        * Cosmetic fix to busybox.c (Don't print a comma at the
            end of line if there are no more application names).
        * Fixed a stupid bug in "head" option handling ("head -n" 
            would segfault).
        * Moved commonly used functions "xmalloc()" and "exit()"
            to utility.c (with proper #ifdef's).
        * Created a tiny tail implementation, removing -c, -q, -v, and making
            tail -f work only with a single file.  This reduced tail from 6k to
            2.4k.  The bigger/more featured tail can still be had by disabling
            BB_FEATURE_SIMPLE_TAIL in busybox.defs.h
        * Ping now falls back to doing the right thing if /etc/protocols
            turns up missing.
        * Fixed mount and umount.  Previously they could leak loop device 
            allocations, causing the system to quickly run out.  Fix for umount
            by Ben Collins <bcollins@debian.org>, and mount was fixed by me.
        * ls formatting on eight charactor user names fixed by 
            Randolph Chung <tausq@debian.org>.
        * cp could, when copying symlinks, change permissions of the
            files pointed to by the symlinks.
        * Several fixes from Pavel Roskin <proski@gnu.org>:
            - `chown' with 1 argument displayed the error incorrectly
            - `fdflush', `length' and `printf' crashed if run without arguments
            - `fdflush' tried to flush itself using *argv
            - added "skip" and "seek" to dd.
            - ls no longer messus up output when combining files and
              directories on the command line 
        * swapoff -a was not working.  Now it is.  
        * init did not cleanly unmount filesystems on reboot.  Now it does.  
        * "sed -ne s/foo/bar/" worked but "sed -n -e s/foo/bar/" didn't.
            Now both work.
        * Some architectures (PowerPc) assume chars are unsigned, so they could
            not distinguish between EOF and '\0xFF' in sed.  Sed now uses ints.
        * Began converting error handling to use some common routines
            in utility.c
        * syslogd now has better message handling and ignores SIGHUP.
        * install.sh had a bug preventing installation to the specified
            target directory.  Fix from Gilbert Coville <gilbert@mvista.com>
        * You can now spefify alternative strip commands -- change 
            also from Gilbert Coville.

        * New Apps: wc, hostid, logname, tty, whoami, yes -- all contributed 
            by Edward Betts <edward@debian.org>
        * Fixed a bug in both cp and mv preventing 'cp foo/README bar'
            type commands (file in a directory to another directory) from
            working.
        * Fixed a logger bug that caused garbage to be written to the syslog 
            (unless you used busybox syslog, which hid the bug).  Thanks to
            Alex Holden <alex@linuxhacker.org> for the fix.
        * /bin/true and /bin/false were echoing a blank line when run.  
            Now fixed.
        * mkdir -p would print an error when asked to mkdir an existing dir
            with no interveining subdirectories.
        * Fixed "syslogd -O" so that it works.  Added -o loop option for mount,
        * and support in umount for loop
          devices. Support is toggled by MOUNT_LOOP feature -- Ben Collins
          <bcollins@debian.org>
        * Several fixes from Marco Pantaleoni <panta@prosa.it> compile in
        * fullWrite() not only if BB_TAR is defined, but also
                if BB_CP or BB_MV are (fullWrite() is referenced by copyFile())
            * add some compiler optimizations to further reduce executable size
                (as a side note, on my machines the largest code is generated
                by gcc 2.95.2 with -Os ! The smallest by plain gcc 2.7.2.3 with
                -O2 -m386 ...)
            * Compile now won't fail if busybox.def.h defines 
                BB_FEATURE_LINUXRC but not BB_INIT.  (init_main used to be
                referenced, but not compiled)
        * Fixed a bug in setting TERM for serial console support.  TERM now
            defaults to "ansi" for serial consoles.
        * Fixed a bug in handling the CONSOLE env. variable for serial
        * consoles.

        * New Apps: sort, uniq. -beppu New Apps: lsmod, rmmod -erik New Apps:
        * fbset contributed by Randolph Chung <tausq@debian.org>.  New App::
        * loadacm contributed by Peter Novodvorsky <petya@logic.ru>
            for loading application character maps for Unicode fonts.
        * Major init re-work.  init now supports inittab (slightly different
            but similar to sysvinit), allowing me to get all the policy out of
            init and into the conf file.  It works just fine without inittab
            being present, but if you dont like the defautl behavior you can
            now do something about it.  Init is much cleaner as a result.
        * Fixed an bug in syslogd causing it to stop after 20 minutes. -erik
        * Fixed an embarrasing segfault in head -beppu Fixed the embarrasing
        * failure of 'logger -p'. -erik Added the -s option to du -beppu
        * Re-worked the source tree a bit so it will compile under glibc 2.0.7 
            with the 2.0.x Linux kernel.
        * Added 'grep -q' thanks to a patch from "Konstantin Boldyshev" 
            <konst@voshod.com>.
        * Grep -i previously failed on UPPER CASE patterns due to a silly 
            regexp implementation bug that is now fixed.
        * Fixed a bug where tar would set, and then clear SGID and SUID bits.
        * Fixed a bug where tar would not set the user and group on device
            special files.
        * Fixed a bug where tar would not restore the time to files.  Fixed a
        * major security problem with tar -- it changed ownership 
            of any file pointed to by a symlink to 777 (like say libc....)
            Ouch!!!
        * cp and mv were very broken when moving directories.  I have rewritten 
            them so they should now work as expected. 
        * sed now supports addresses (numeric or regexp, with negation) and 
            has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
        * Fixed dmesg.  It wasn't parsing its options (-n or -s) properly.
        * Some cosmetic fixes to ls output formatting to make it behave more
            like GNU ls.
        * Fixed a stupid segfault in kill.  Several fixes from Friedrich Vedder
        * <fwv@myrtle.lahn.de>:
            - Added gunzip -t, removed gunzip.c dead code,
            - fixed several typos
            - Glibc 2.0.7 and libc5 compile fixes
        * Fixed a bug where 'mknod --help' would segfault.

        * New Apps: ping, hostname, and mkfifo contributed by Randolph Chung
            <tausq@debian.org>.  3 items off the TODO list!
        * I wrote free (just calls "cat /proc/meminfo").  Added tail, based on
        * tail from GNU textutils-1.19, but adjusted
            to suit my evil purposes.  Costs 6k.  I'll make it smaller
            sometime.
        * on reboot, init called 'umount -a -n', which caused errors
            when BB_MTAB was not enabled.  Changed to 'umount -a', which does
            the right thing.
        * init will now try to run /sbin/getty if it is present (for easy
            integration with the about-to-be-released tinylogin.)
        * kill now behaves itself properly, added 'kill -l' to list signals 'ls
        * -l' was failing on long directories, since my_getid was leaking 
            one file descriptor per file.  Oops.
        * Fixed rebooting from init.  I'd accidently left some debugging code
        * in
            which blocked reboots.
        * Fixed reboot, halt (and added poweroff) such that they handle it when
            init is not at PID 1 (like when running in an initrd).
        * Added a prelinary du implementation.  Some parameter parsing
            stuff still needs to be added. -beppu (John Beppu
            <beppu@lineo.com>)
        * Implemented tee.  -beppu Implemented head. -beppu

        -Erik Andersen, Dec 10, 1999

0.38
        * Fixed a segfault in 'umount -a' when a badly formed /etc/fstab
            file existed.
        * df will not exit on error, but will stat all mounted filesystems.
        * Fixed tar so uid/gid/permissions on extracted tarballs will be 
            correct.
        * Fixed find -name so it properly uses shell wildcard patterns 
            (i.e. `*', `?', and `[]') instead of regular expressions, which
            was causing some confusing and unexpected behavior.
        * Added klogd to syslogd, so now the log will contain both system and
            kernel messages.
        * syslogd now creates the /dev/log socket to make sure it is there, and
            is actually a socket with the right permissions.
        * I've taken a first step to making busybox not need the /proc 
            filesystem.  Most apps don't need it.  Those that _require_ it, 
            will complain if you enable them when you disable 
            BB_FEATURE_USE_PROCFS.
           
        -Erik Andersen, Dec 5, 1999

0.37
        * Wrote a micro syslogd, and a logger util (to log things to the syslog
            from the command line or scripts)  With both compiled in, costs 4k.
        * Fixed 'make install' so symlinks are installed in their proper
        * locations.  Changed the build system slightly so that features can
        * now be enabled
            or disabled from the busybox.defs.h header file, without trying to
            compile in a source file named after that featue (unless that file
            exists).
        * Several options are now moved into busybox.defs.h Now 'rm -R' and 'rm
        * -r' both work.  dd now properly handles input beyond 1 block from
        * stdin.  Fixed a bug where tar unpacked everything a directories.
        * Moved some code 
            from createPath into mkdir where it belonged, thereby making tar
            work properly.
        * Fixed an off-by-one bug in cat.  Given a list of file it wouldn't cat
        * out the
            last file in the list.
        * Fixed 'ls -ln' so numeric group/uid are presented properly, and fixed
        * 'ls -l' 
            so when uid/gid is not in /etc/{passwd,group} the numeric group/uid
            are presented properly.  
        * Also added a TODO.


        -Erik Andersen, Nov 25, 1999

0.36
        * fixed dd so it properly defaults to stdin and stdout when no 
            if= and of= are set (fix thanks to Eric Delaunay).
        * Don't try to close the file descriptor of a pipein tar. (fix also
        * from
            Eric Delaunay).
        * Made createPath be quiet (again thanks to Eric Delaunay).  If
        * BB_CONSOLE_CMD_IF_RC_SCRIPT_EXITS is defined, then whatever
            command you define it as will be run if the init script exits.
        * Updated install.sh to make it more robust (thanks to Adam Di Carlo)
        * NFS support added to mount by Eric Delaunay.  It costs 10k when
        * compiled
            in, but that is still a big win for those that use NFS.
        * Made 'rm -f' be silent for non-existant files (thanks to Eric
        * Delaunay).  changed zcat.c to gunzip.c.  It now obeys the principle
        * of least surprise 
            and acts as god intended gunzip and zcat to act.  They answer
            --help and obey the '-c' flag.
        * Fixed a bug in mv which caused it to not move files when the
        * destination
            was a directory.
        * Fixed a decimal-instead-of-octal bug causing mkdir to make
        * directories
            with very wrong permissions.
        * chmod would overwrite file permissions instead of modifying them.
            Now it properly modifies permissions.
        * Init now sends warnings destined for the console to /dev/console to
        * ensure
            they show up on whatever the active console it.  Otherwise
            important messages (for example that the system is rebooting) were
            not seen when switched to a different VT.

0.35
        * gzip now obeys the principle of least surprise and acts like god
        * intended 
            (i.e. it accepts a file name, answers --help, and obeys the '-c'
            flag and only then outputs to stdout).
        * Fixed more.c to compile autowidth on sparc and set initial winsize 
            to 0,0 in case the TIOCGWINSZ ioctl fails.  Fix thanks to Eric
            Delaunay.
        * Fixed tar so it now works as expected (it had TRUE/FALSE backwards)
        * tar now accepts --help chmod, chown, and chgrp usage now works
        * General usage (i.e. --help) cleanups for most apps umount now parses
        * options correctly tar can now unpack tarballs containing device
        * special files, 
            sockets, and fifos (though it can't pack them up) thanks to Matt
            Porter.  Creating archives containing these is still left to the
            interested student.
        * fixed up the license in more.c to properly point to Bruce Perens.

        -Erik Andersen, Nov  11, 1999

0.34
        * ls -l now displays link names outside the current directory,
            Patch thanks to Eric Delaunay
        * init now properly handles sparc serial consoles and does a
            better job of finding the real console device rather than using
            /dev/console which doesn't support job control. Patch also thanks
            to Eric Delaunay.
        * more started to read from stdin after the last file was finished, and 
            options were not parsed correctly (fix thanks to Eric Delaunay).
        * more will now use the terminal size if BB_FEATURE_AUTOWIDTH is on.
        * rm wouldn't remove a symlink unless the symlink was valid.  This was
            a side effect of the busybox 0.32 recursiveAction() fix.  Things
            should now work correctly.
        * grep wouldn't grep stdin.  Now it does.  sed wouldn't sed stdin.  Now
        * it does.  sed was appending a \n to the end of lines with
        * replacements.
            Now it doesn't do that.
        * ls -l now bypasses libc6 nss when displaying user/group names.
            Now uses my_getpwuid and my_getgrgid.

         -Erik Andersen, Nov  8, 1999

0.33
        * Fixed a bug where init could hang instead of rebooting.
        * Removed some debugging noise from init.c
        * Fixed ln so it works now (it was very broken).
        * Fixed df so it won't segfault when there is no /etc/fstab,
        * If BB_MTAB is not defined, df and mount will whine if /etc/fstab
            is not installed (since they cannot fixup "/dev/root" to 
            state the real root device name)
        * merged some redundant code from mtab.c/df.c into utility.c

         -Erik Andersen, Nov  5, 1999

0.32
        * More changes -- many thanks to Lineo for paying me to work on
            busybox.  If you have any problems please let me know ASAP at
            andersen@lineo.com or andersee@debian.org
        * usage() now prints the BusyBox version.  This will help folks
            realize that they are not in Kansas anymore.
        * Fixed mkdir -m option so that it works.  kill segfaulted w/o any
        * arguments.  Now it doesn't do that.  kill wasn't properly accepting
        * signal names.  It does now.  Added new apps chvt and deallocvt (I
        * should probably add open) Major rewrite of init.c.  Code is now
        * readable by mere mortals IMHO.  Wrote sed -- weighs only 1.8k (5.8k
        * with full regular expressions!).  Fixed a stupid seg-fault in sync
        * Fixed mount -- mount -a failed to parse and apply mount options Fixed
        * umount -n (patch thanks to Matthew Grant <grantma@anathoth.gen.nz>)
        * umount -a no longer umounts /proc Added BB_MTAB, allowing (at the
        * cost of ~1.5k and the need for a rw /etc)
            folks to use a real /etc/mtab file instead of a symlink to
            /proc/mounts.  mount, and umount will add/remove entries and df
            will now use /etc/mtab if BB_MTAB is defined. 
        * Fixed a nice bug in recursiveAction() which caused it to infinitely
            hunt through /proc/../fd/* creating new file descriptors if it
            followed the /dev/fd link over to /proc.  recursiveAction() now
            lstat's the file when followLinks==FALSE so it won't follow links
            as the name suggests.  Fix thanks to Matt Porter
            <porter@debian.org>.


         -Erik Andersen, Nov  4, 1999

0.31
        * I added a changelog for version 0.30.  adjusted find internals to
        * make it smaller, and removed 
            some redundancy.
        * Fixed a segfault in ps when /etc/passwd or /etc/group 
            are absent.  Now will warn you and carry on.
        * Added in optional _real_ regular expression support (to be
            the basis for a future sed utility).  When compiled in it adds
            3.9k, but makes grep much more capable.
        * Checked out using nftw(3) for recursive stuff, but unfortunatly
            it wasn't supported before GNU libc 2.1, and some folks use glibc
            2.0.7 since it is much smaller than that latest and greatest.

         -Erik Andersen, Oct 21, 1999

0.30
        Major changes -- lots of stuff rewritten. Many thanks to Lineo for
        paying me to make these updates. If you have any problems with busybox, 
        or notice any bugs -- please let me know so I can fix it.  These 
        changes include:

        Core Changes:
            * busybox can now invoke apps in two ways: via symlinks to the
                busybox binary, and as 'busybox [function] [arguments]...'
            * When invoked as busybox, the list of currently compiled in 
                functions is printed out (no this is not bloat -- the list has
                to be there anyway to map invocation name to function).
            * busybox no longer parses command lines for apps or displays their
                usage info.  Each app gets to handle (or not handle) this for
                itself.
            * Eliminated monadic, dyadic, descend, block_device, and 
                postprocess.  It was cumbersome to have so many programs
                cobbled together in this way.  Without them, the app is much
                more granular.
            * All shared code now lives in utility.c, and is properly
                ifdef'ed to be only included for those apps requiring it.
            * Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
                so now each app has the function prototype of (da-dum): extern
                int foo_main(int argc, char** argv); which speeds integration
                of new apps.
            * Adjusted the Makefile to make it easier to 
                {en|dis}able debugging.
            * Changed default compiler optimization to -Os 
                (optimize for smaller binaries).

        App Changes:
            * To cope with the new app function prototype and the removal of
                monadic, dyadic, etc, the following apps were re-written:
                    * cat - Works same as always.  chgrp, chmod, chown -
                    * rewrite.  Combined into a single 
                        source file.  Absorbed patches from Enrique Zanardi
                        <ezanard@debian.org> that removes the dependency on
                        libc6 libnss* libraries.
                    * cp - Can now do 'cp -a' can can copy devices,
                        pipes, symlinks, as well as recursive or non-recursive
                        dir copies.
                    * fdflush - adjusted to remove dependancy on struct
                    * FileInfo.  find - Now includes some basic regexp matching 
                        which will be the basic of a future mini-sed.
                    * ln - Same functionality.  mkdir - Added -p flag to
                    * feature set.  mv - rewrite.  rm - Added -f flag to
                    * feature set.  rmdir - Same functionality.  swapon,
                    * swapoff - Combined into a single binary. No longer
                        uses /etc/swaps.  swap{on|off} -a uses /etc/fstab
                        instead.
                    * touch - Same functionality.  date - adjusted with a patch
                    * from Matthew Grant <grantma@anathoth.gen.nz>
                to accomodate glibc timezone support.  I then ripped out GNU
                getopt.
            * mkswap -- new version merged from util-linux.  Can now make 
                        >128Meg swaps.  
                * Replaced the old and star, unstar, and tarcat with the tar 
                        implementation from sash.   Now tar behaves as god intended it
                        to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
            * dd -- rewritten.  Can with with files, stdin, stdout.  Added the
            * following new apps: loadfont -- added from debian boot floppies
            * chroot -- added based on a patch from Paolo Molaro
            * <lupus@lettere.unipd.it> grep -- I just wrote it.  Only matches
            * simple strings ps -- I just wrote it.  Has _no_ options at all,
            * but works.  fsck_minix, mkfs_minix -- added from util-linux, but
            * I ripped out
                        internationalization and such to make them smaller.
                    * sfdisk -- Added from util-linux (minus
                    * internationalization and such).  Probably some other
                    * changes that I forgot to document...
