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.
