BusyBox

BusyBox provides many common UNIX utilities in a single small executable for embedded systems. The community 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.

Installation

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.

Usage

init

Init scripts can be used together with busybox-init, for example minirc-git^AUR. See init for details.

getty

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, you just put this line in /etc/inittab.

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 the gettty, then replace respawn with .

mdev

See Gentoo:mdev.

runit

See runit.

gollark: I wouldn't be surprised if at least a few % of Apple devices were primarily bought for iOS development.

gollark: Yes, that too.

gollark: Which I don't think is worth it in most cases given the other tradeoffs.

gollark: Anyway, their software is... allegedly good, in some ways - I don't really like Apple's attitude in designing it, or much of what it does, and it's becoming increasingly locked down and uncool - but you're paying several hundred $ for that software.

gollark: Yes, of course.
