Eric Andersenb186d981999-12-03 09:19:54 +00001TODO list for busybox in no particular order. Just because something
2is listed here doesn't mean that it is going to be added to busybox,
3or that doing so is even a good idea. It just means that I _might_ get
4around to it some time. If you have any good ideas, please let me know.

Erik Andersen1c5b2581999-12-16 20:59:36 +00006* login/sulogin/passwd/getty/etc are part of tinylogin, and so are not
Erik Andersen94f5e0b2000-05-01 19:10:52 +00007 needed or wanted in busybox (or else I'd have to link to libcrypt).

Eric Andersenc5cd4702001-01-24 18:47:30 +00009* We _were_ going to split networking apps into a new package called
10 netkit-tiny. Per discussions on the mailing list, this isn't going
Eric Andersen8ec10a92001-01-27 09:33:39 +000011 to happen. False alarm. Sorry about the confusion.

13* The busybox shell, lash, is really too weak for serious use, although it is
Eric Andersen09580932001-04-10 20:10:55 +000014 possible to run many simple systems with it. BusyBox 0.49 was supposed to
15 have a new shell, updated to understand full Bourne grammer. Well, that
16 simply didn't happen in time for the release. A rewrite is in progress
17 that will result in a new shell that understands the full Bourne grammar.
18 This new shell is being championed by Larry Doolittle
19 <ldoolitt@recycle.lbl.gov>, and could use your help. Please see the work
20 in progress at http://doolittle.faludi.com/~larry/parser.html and help
21 us out.

44reveals the list of all external (i.e. libc) things that BusyBox depends on.
Eric Andersen235f66d2000-12-13 18:07:38 +000045It would be a very nice thing to reduce this list to an absolute minimum, to
Eric Andersenc5cd4702001-01-24 18:47:30 +000046reduce the footprint of busybox, especially when staticly linking with
47libraries such as uClibc.
