-Compile with debugging on, run 'nm --size-sort ./busybox'
-and then start with the biggest things and make them smaller...
+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.
-busybox.defs.h is too big and hard to follow.
+(BTW, this is more informative if BB_FEATURE_NFSMOUNT is turned off...)
-Perhaps I need to add a better build system (like the Linux kernel?)
-
------------------------
+Most wanted list:
+ [andersen@slag busybox]$ grep -l getgroups *.[ch]
+ test.c
-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).
-
+Policy violation. getgroups uses libc nss, which is unlikely
+to be present in an embedded system.

-> 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,

+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):
