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 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 (network logging) will remain in BusyBox.

* dnsdomainname
|
|
* traceroute/netstat
|
|
* hwclock
|
|
* stty
|
|
* tftp
|
|
* ftp
|
|
* group/commonize strings, remove dups (for i18n, l10n)

|
|
Running 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.
|
|
|
|
-----------------------
|
|
|
|
Compile with debugging on, run 'nm --size-sort ./busybox'
|
|
and then start with the biggest things and make them smaller...
|
|
|
|
-----------------------
|
|
|
|
du.c probably ought to have an -x switch like GNU du does...
