 TODO list for busybox in no particular order. Just because something
 is listed here doesn't mean that it is going to be added to busybox,
-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 in 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.

 -----------
 
-* Allow tar to create archives with sockets, devices, and other special files
-* Make insmod actually work
-* dnsdomainname
-* traceroute/netstat
-* rdate
-* hwclock
-* killall
-* stty
-* tr
-* cut
-* expr (maybe?)  (ash builtin?)

-busybox.defs.h is too big and hard to follow.
-
-I either need to add a better build system (like the Linux kernel?)
-or I need to split up busybox.defs.h into coherent chunks (i.e.
-busybox.defs.h just has a bunch of: 
-
-#include "fileutils.h"
-#include "shellutils.h"
-
-which would then have smaller sets of #defines...
-Hmm.  Needs to be carefully thought out.
+Possible apps to include some time:
 
------------------------
-
-
-
-Some known bugs, todo items, etc...
-
------------------------
+* group/commonize strings, remove dups (for i18n, l10n)

+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.

-#1 You are storing by id instead of name like normal tar. Did you realize this?
-(or am I missing some compile option? )ctar did not do this, and I don't think
-it's a good idea for LRP.
+Run the following:
 
-#2
-ctar did not produce the EOF error like your tar does. I believe you need to
-pad the end of the archive with at least 2 tarsized (512byte) blocks. (I
-think???)
-
-#3
-There is no exclude file(s) option to tar. LRP's packaging system can not
-function without this. Will you have the time to add this soon?

+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, to
+reduce the footprint of busybox, especially when staticly linking with
+libraries such as uClibc.

-
-/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).
+Compile with debugging on, run 'nm --size-sort ./busybox'
+and then start with the biggest things and make them smaller...

-Today, "mv" behaved as a cp -a and my disk becomed full. It does not
-work properly either when renaming a directory into something else
-(it produces a lot of disk activity when doing this).
+xargs could use a -l option

+libbb/unzip.c and archival/gzip.c have common constant static arrays and
+code for initializing the CRC array. Both use CRC-32 and could use
+common code for CRC calculation. Within archival/gzip.c, the CRC
+array should be malloc-ed as it is in libbb/unzip.c .
