-* Allow tar to create archives with sockets, devices, and other special files
-* Make insmod actually work
* dnsdomainname
* traceroute/netstat
-* rdate
* hwclock
-* killall
* stty
-* tr
-* expr (maybe?) (ash builtin?)
+* tftp
+* ftp
+* group/commonize strings, remove dups (for i18n, l10n)

+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.

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