BusyBox
Contents
Installation
Install busybox from the official repositories.
Busybox commands are symbolic links to /usr/bin/busybox
and thus take very little space. This is especially interesting for low-footprint systems. Several packages in the AUR replace the GNU utilities with these symbolic links.

Minirc provides an init script compatible to busybox-init. See init for details.
