Loic posted an article on
debian-administration about downloadable images for Linux distributions.
He provides the images via rsync:
rsync rsync://packaging-farm.dachary.org/packaging-farm/
and provides images for Debian etch, lenny, unstable - Ubuntu dapper, edgy, feisty, gutsy - Fedora fc5, fc6 and f7
Pretty useful idea. People using vmware have of course a bigger list of downloadable images via the
virtual appliances for vmware where you can even get an
image for grml.
