Mach allows you to set up clean roots from scratch for any distribution or distribution variation supported.

this clean build root can be used for several goals:
- making clean packages
- set up chroots for services to run it
- make disk images of clean roots (for example for uml)
currently, mach works for rpm-based distributions that can work with apt for rpm.

included at this moment is the necessary information to set up:
- fedora 1, 2, 3, 4, 5, 6, and development
- red hat 7.0, 7.1, 7.2, 7.3, 8, and 9
- centos 4
- dave/dina
- conectiva 9
- suse 8.1, 8.2, and 9.0
- yellowdog 2.3, and 3.0
some handy features of mach include:
- "caching" of downloaded packages using the build hosts's apt
the build root
- ensures clean packages by reverting to the base set of build packages
- uses apt to resolve dependencies
- parsing of buildrequires to install necessary packages for building
- build ordering when doing multiple builds
- support for flavours of distribution
- multiple build roots
- locking of buildroot to avoid concurrent builds
- optional signing of built packages
