Installing a Debian schroot with debfactory

I have recently had the need to teste a package on Debian Lenny, it was a good reason to add support for Debian on the debfactory schroot_build.py script.
Durint testing I have found bug 557316, you will need to add http://ftp.debian.org/debian to /etc/apt-cacher-ng/backends_debian before proceeding.

To create and test on a Debian Lenny schroot just run:

bzr branch lp:debfactory && sudo debfactory/bin/schroot_build.py -c /home/chroot -p debian -d lenny -a i386 && schroot -c lenny.i386 -p
