or that doing so is even a good idea. It just means that I _might_ get
around to it some time. If you have any good ideas, please let me know.
-* login/sulogin/passwd/getty/etc are part of tinylogin, and so are not
- needed or wanted in busybox (or else I'd have to link to libcrypt).
-
-* Networking apps are probably going to be split out some time soon into a
- separate package (named perhaps netkit-tiny?). This would remove the
- following items from BusyBox: hostid, hostname, nc, nslookup, telnet,
- and ping. nfs mounting and syslogd (when it supports network logging)
- will remain in BusyBox.
+* We _were_ going to split networking apps into a new package called
+ netkit-tiny. Per discussions on the mailing list, this isn't going
+ to happen. False alarm. Sorry about the confusion.

-Bugs that need fixing before the 0.44 release goes out the door:
-
- - "more" doesn't accept " " to scroll by one page when BB_FEATURE_USE_TERMIOS
- is not on.
- - doc / website updates to tell what the real mailing list is for busybox.
- - fix 'cp' (or test suite script) so that it passes the test suite.
-
-These could get done before the 0.44 release if we have time, but we won't
-hold up the 0.44 release just because of these:
-
- - ps dirent race bug (need to stat the file before attempting chdir)
- - Make 'ln -s /tmp/file .' work the way GNU ln does (i.e. makes a link to
- /tmp/file in the current directory, rather then trying and failing to create
- a symlink named "." in the current working directory).
- - Prune sfdisk
- - Graft fdisk
-
-These will be deferred til after 0.44 is released. We will rework these to use
-libc regex functions instead (as per the mailing list discussion):
-
- - 'grep foo$ file' doesn't work
- - 'grep *foo file' segfaults
+Possible apps to include some time:
+* group/commonize strings, remove dups (for i18n, l10n)
-----------
-* Make insmod actually work
-* dnsdomainname
-* traceroute/netstat
-* rdate
-* hwclock
-* stty
-* expr
-* wget (or whatever I call it)
-* tftp
-* ftp
-* group/commonize strings, remove dups (for i18n, l10n)
-* consider making a unified option parser (if it can be done modular, small, etc.)
+With sysvinit, reboot, poweroff and halt all used a named pipe,
+/dev/initctl, to communicate with the init process. Busybox
+currently uses signals to communicate with init. This makes
+busybox incompatible with sysvinit. We should probably use
+a named pipe as well so we can be compatible.
-----------------------
-Running the following:
+Run the following:
rm -f busybox && make LDFLAGS+=-nostdlib 2>&1 | \
sed -ne 's/.*undefined reference to `\(.*\)..*/\1/gp' | sort | uniq
-reveals the list of all external (i.e. libc) things that BusyBox depends on.
-It would be a very nice thing to reduce this list to an absolute minimum, and
-then create a microLibc to provide these functions. There is no good reason
-for GNU libc to be so big. I'm sure it can be a lot better.
-
-(BTW, this is more informative if BB_FEATURE_NFSMOUNT is turned off...)
-
-Most wanted list:
-
- [andersen@slag busybox]$ grep -l getgroups *.[ch]
- test.c
-
-Policy violation. getgroups uses libc nss, which is unlikely
-to be present in an embedded system.
-
-To be replaced with a busybox local glob routine:
-
- [andersen@slag busybox]$ grep -l glob *.[ch]
- gunzip.c
- gzip.c
- sh.c
- tar.c
- telnet.c
-
-Can check_wildcard_match() from utility.c do this job?
-
+reveals the list of all external (i.e., libc) things that BusyBox depends on.

-----------------------
-----------------------
-busybox.defs.h is too big and hard to follow.
-
-Perhaps I need to add a better build system (like the Linux kernel?)
-
------------------------
-
-Feature request:
-
-/bin/busybox --install -s which makes all links to commands that it
- can support (an optionnal -s should be used for symbolic links instead
- of hard links).
-
------------------------
-
-
-> Have you ever thought of doig network logging in busybox syslogd ? It
-> would quite make sense on embedded systems... :)
-
-So far I had not considered it. Basically, you wish to have
-messages from the embedded box logged to a remote network
-syslog box, right? I can see that this would be useful.
-I'll add this to the TODO list,
-
-
------------------------
-
-
- I think that the add_inode &c in utility.c needs to also stow the
- st_dev field, and that du.c should NOT call `reset_inode_list'
- because there can be hard links from inside one argv/ to inside
- another argv/. du.c probably ought to have an -x switch like GNU du
- does also...
-
+xargs could use a -l option
------------------------------------------------------------------
-An interesting email listing some apps that use /proc. BusyBox
-tries to avoid /proc as mush as is possible, so this stuff is
-interesting (to me at least):

-
-As a point of reference, here's a slightly tweaked analysis of the
-programs on the system I'm reading your mail on. Basically, I ran the
-following script...
-
- Q> #!/bin/bash
- Q> function use() {
- Q> for Z in $* ; do
- Q> strings $Z | grep /proc | sed "s=^=$Z ="
- Q> done
- Q> }
- Q> use /{,s}bin/* /usr/{,s}bin/* | sort -u | tee proc-usage
-
-...and then went through it removing comments and print format
-strings. Replace /proc with /dev and you'd soon have an equivalent
-list for that - although I can report that such is MUCH larger...
-
-There are three programs therein that refer to /proc/mounts ...
-
- /bin/mount
- /bin/umount
- /usr/bin/eject
-
-...and, as you stated, none that refer to /proc/atm on this system.
-However, as this is a RedHat Linux 5.0 based system, that's not
-necessarily an up to date reference thereto...
-
-Here's the list anyway...
