@@ -3,26 +3,62 @@ 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

-* Allow tar to create archives with sockets, devices, and other special files
-* Add in a mini insmod, rmmod, lsmod
-* init clearly needs to support some type of minimalist /etc/inittab. I
-    currently have _way_ too much policy hardcoded in the source.  Adding
-    support for getty has made me realize how much that sucks.
-* dnsdomainname
-* traceroute/nslookup/netstat
-* rdate
+Possible apps to include some time:
+
 * hwclock
-* killall
-* stty
-* sort/uniq
-* wc
-* tr
-* expr (maybe?)  (ash builtin?)
+* group/commonize strings, remove dups (for i18n, l10n)
+* login/sulogin/passwd/etc are part of tinylogin.  These are 
+    being merged into busybox as time allows.

+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.

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