Gentoo is a source based distribution.
After the bootstrap step, the installation of all the software is done from the source.
Main strong points:
Because Gentoo is normally built using a chroot, building a UML instance only requires minor tweaks after following the standard installation instructions, using the host and a loopback mounted filesystem instead of booting from an install CD.
These images are on an ext3 filesystem and use 2GB of diskspace.
This is the multilib profile version, which supports both x86 and AMD64
