RPM Based Distribution Chroot
A while back I wrote a small shell script to bootstrap an rpm based distribution, it currently "doesn't work" (tm) with modern systems... the code is available via git via either the git://git.sommitrealweird.co.uk/rpmbased-dist-chroot.git url or http://git.sommitrealweird.co.uk/rpmbased-dist-chroot.git - it's also available via git web at http://git.sommitrealweird.co.uk/gitweb?p=rpmbased-dist-chroot.git.
The last release is available from /downloads/rpmbased-dist-chroot-0.1.1.tar.gz.
