Eric Andersenb186d981999-12-03 09:19:54 +0000[diff] [blame]1TODO 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 Andersen94f5e0b2000-05-01 19:10:52 +0000[diff] [blame]7 needed or wanted in busybox (or else I'd have to link to libcrypt).

Eric Andersenc5cd4702001-01-24 18:47:30 +0000[diff] [blame]9* 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 +0000[diff] [blame]11 to happen. False alarm. Sorry about the confusion.

Eric Andersenb0aca922001-05-03 17:35:48 +0000[diff] [blame^]13* The default busybox shell, lash, is really too weak for serious use,
14 although it is possible to run many simple systems with it. BusyBox
15 0.52 now contains a rewritten shell, hush, which understands most
16 Bourne grammar, with only about a 4 Kbyte binary size penalty. You can
17 engage hush at pre-compile time by "ln -sf hush.c sh.c; touch hush.c".
18 Hush is young, and has plenty of bugs to shake out, so think twice before
19 using it for production systems. We welcome bug reports and patches.

Eric Andersenb0aca922001-05-03 17:35:48 +0000[diff] [blame^]32With sysvinit, reboot, poweroff and halt all used a named pipe,
33/dev/initctl, to communicate with the init process. Busybox
34currently uses signals to communicate with init. This makes
35busybox incompatible with sysvinit. We should probably use
36a named pipe as well so we can be compatible.

45reveals the list of all external (i.e. libc) things that BusyBox depends on.
Eric Andersen235f66d2000-12-13 18:07:38 +0000[diff] [blame]46It would be a very nice thing to reduce this list to an absolute minimum, to
Eric Andersenc5cd4702001-01-24 18:47:30 +0000[diff] [blame]47reduce the footprint of busybox, especially when staticly linking with
48libraries such as uClibc.
