@@ -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 
+    netkit-tiny.  Per discussions on the mailing list, this isn't going
+    to happen.  False alarm.  Sorry about the confusion.  
+
+* The busybox shell, lash, is really too weak for serious use, although it is
+    possible to run simple systems with it.  BusyBox 0.49 was supposed to have
+    a new shell, updated to understand full Bourne grammer.  Well, that simply
+    didn't happen in time for the release.  A rewrite is in progress that will
+    result in a new shell that understands the full Bourne grammar.  This new
+    shell is being championed by Larry Doolittle <ldoolitt@recycle.lbl.gov>, and
+    could use your help.  Please see the work in progress at
+       http://doolittle.faludi.com/~larry/parser.html

 -----------
 
-* 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)?
+* group/commonize strings, remove dups (for i18n, l10n)

+Write a fixup_globals function to do just that right before calling
+non-forking applets.  Or, just always fork...

+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...
