Hi, I packaged schroot, because I find it very useful (for the Firebird project, all our snapshots builds are done with it, and with lvm snapshots we have a clean env for running tests)
I took the Fedora package as a starter, but it need some debugging to be fully integrated to Mageia so if someone want to co maintain it with me, your are welcome about schroot : http://wiki.debian.org/RichardDarst/Schroot man schroot and exemple of use with lvm snapshots : http://www.pseudorandom.co.uk/2007/sbuild/
