@@ -3,29 +3,55 @@ 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).
+
+* We _were_ going to split networking apps into a new package called

+    to happen.  False alarm.  Sorry about the confusion.

 -----------
 
-* Allow tar to create archives with sockets, devices, and other special files
-* Add in a mini insmod, rmmod, lsmod
-* Change init so halt, reboot (and poweroff) work with an initrd
-    when init is not PID 1
-* poweroff
-* du
-* mkfifo
-* hostname/dnsdomainname
-* ping/traceroute/nslookup/netstat
-* rdate
+Possible apps to include some time:
+
 * hwclock
-* login/getty
-* free
-* killall
-* tee
-* stty
-* head/tail
-* sort/uniq
-* wc
-* tr
-* expr (maybe)?
+* start-stop-daemon
+* group/commonize strings, remove dups (for i18n, l10n)
+
+-----------
+
+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
