Busybox commands are simply symlinks to the busybox binary and are thus extremely light weight. For a low footprint system, this could be quite valuable.
This package offers a nearly pain-free drop-in replacement of the GNU coreutils. Some commands lack options present in the corresponding coreutils binaries (current problems: Yaourt and readline).
Gain from replacing coreutils with busybox: coreutils: 13.1 MB installed, symlinks to busybox: approximately 0.
- Busybox-init: a very simple (only 1 runlevel) init system, ash init scripts
