3. Some distributions such as Debian are desktop type distributions that have been ported to the ARM processor family These distributions will give much flexibility in terms of application availability and an active developer community These distributions will typically take a reasonably large amount of disk space and will likely be inappropriate for installation into a flash disk Applications are typically distributed as precompiled binaries with little configuration of optimization levels etc Some distributions such as the ucLinux distribution are geared toward embedded projects with limited storage space These distributions can normally be tailored for an custom installation and will generally produce the smallest footprint file systems They generally have a more limited developer community so they may require more custom work for a given task The applications here are typically compiled from scratch and a lot of times they are cross built from the IA Linux host This gives fine grained control over optimization levels etc Linux Debian Installation Guide Intel I O Processors March 2006 Order Number 306507003US E Linux Debian Distributions l ntel 6 1 March 2006 Installing Debian See http www debian org for more information on the Debian distribution There are three main branches of Debian stable currently codenamed Woody testing currently codenamed Sarge and unstable currently codenamed Sid Se
