busybox/TODO

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.

* Make insmod actually work
* dnsdomainname
* traceroute/netstat
* rdate
* hwclock
* stty
* cut
* expr (maybe?)  (ash builtin?)



-----------------------

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


-----------------------


busybox.defs.h is too big and hard to follow.

Perhaps I need to add a better build system (like the Linux kernel?)

-----------------------


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?


-----------------------

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).


-----------------------

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...

Hi there.

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...
