* 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 tiny-netkit?). This currently includes
- hostid, hostname, mnc, and ping.
-
+* 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.
+
+* The default busybox shell, lash, is really too weak for serious use,
+ although it is possible to run many simple systems with it. BusyBox
+ 0.52 now contains a rewritten shell, hush, which understands most
+ Bourne grammar, with only about a 4 Kbyte binary size penalty. You can
+ engage hush at pre-compile time by "ln -sf hush.c sh.c; touch hush.c".
+ Hush is young, and has plenty of bugs to shake out, so think twice before
+ using it for production systems. We welcome bug reports and patches.

-* Make insmod actually work
-* dnsdomainname
-* traceroute/netstat
-* rdate
-* hwclock
-* stty
-* cut
-* expr
-* wget (or whatever I call it)
-* tftp
-* ftp
+Possible apps to include some time:
+* hwclock
+* group/commonize strings, remove dups (for i18n, l10n)
------------------------
+-----------
-Add a compile option to turn off all the compiled in help
-and usage information. Some folks don't need or want it...
+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:
- make LDFLAGS+=-nostdlib 2>&1 | sed -ne 's/.*undefined reference to `\(.*\)..*/\1/gp' | sort | uniq
+ 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.
-
+It would be a very nice thing to reduce this list to an absolute minimum, to
+reduce the footprint of busybox, especially when staticly linking with

-----------------------
-----------------------
-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,
-
+ du.c probably ought to have an -x switch like GNU du does...
-----------------------
-
- 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

-
-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...
