BusyBox provides many common UNIX utilities in a single small executable for embedded systems. The package includes runit; see runit for more information.

Note: Do not expect full drop-in replacement and compatibility. Certain utilities may not exist, and for those that do, there may be missing options.


Install the busybox package.

Busybox commands are symbolic links to /usr/bin/busybox and thus take very little space. This is especially interesting for low-footprint systems.



The gettys are defined in the file /etc/inittab. By default, getty is started on ttys 1 through 4.

In order to enable/disable gettys:

tty2::respawn:/sbin/agetty -8 -s 38400 tty2 linux

Just replace tty2 with the tty you want getty to start on. If you want init to ask you before starting getty, then replace respawn with askfirst.
