2.9 Other Operating Systems
Raspbian Linux is not the only OS that you can run on a
Raspberry Pi. Many varieties of Linux have been repackaged so
that you can use them, and there are several non-Linux
operating systems that also work.
Arch Linux
Arch Linux is an extremely lightweight version of Linux that is
ideal for servers or devices with unusual purposes – where many
of the packages that are normally installed to create a usable
desktop environment are not needed. You can download a disk
image of Arch Linux from
http://www.raspberrypi.org/downloads/ or install it from
NOOBS.
RISC OS
RISC OS is available at http://www.raspberrypi.org/downloads/
or you can install it using NOOBS. It has been in use since 1987,
and was designed for Archimedes line of computers made by
Acorn Computers Ltd. These machines used the first ARM
processors.
RetroPie
RetroPie is a customized version of Raspbian that repackages the
OS with a variety of emulators for classic computers and video
games consoles. Find out more at

AEROS
AROS is designed to be a successor to the operating system
AmigaOS, which is itself based on the operating system used by
the Commodore Amiga range of 16-bit computers. The
Raspberry Pi version is called AEROS.
