| Eric Andersen | b186d98 | 1999-12-03 09:19:54 +0000 | [diff] [blame] | 1 | TODO list for busybox in no particular order. Just because something |
| 2 | is listed here doesn't mean that it is going to be added to busybox, |
| 3 | or that doing so is even a good idea. It just means that I _might_ get |
| 4 | around to it some time. If you have any good ideas, please let me know. |

| Eric Andersen | c5cd470 | 2001-01-24 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 Andersen | 8ec10a9 | 2001-01-27 09:33:39 +0000 | [diff] [blame] | 11 | to happen. False alarm. Sorry about the confusion. |

| Eric Andersen | b0aca92 | 2001-05-03 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 Andersen | b0aca92 | 2001-05-03 17:35:48 +0000 | [diff] [blame] | 32 | With sysvinit, reboot, poweroff and halt all used a named pipe, |
| 33 | /dev/initctl, to communicate with the init process. Busybox |
| 34 | currently uses signals to communicate with init. This makes |
| 35 | busybox incompatible with sysvinit. We should probably use |
| 36 | a named pipe as well so we can be compatible. |
