Hi, I forked your make_sysroot.py script to add Debian support. This means that in addition to armhf, you now have armel available as well.
https://gist.github.com/cellularmitosis/3f61f979d09f875fcada
e.g. ./make_sysroot.py --distro debian --version jessie --arch armel --install sysroot.debian.jessie.armel
Also, I added a "cache" directory to keep the ubuntu / debian files distinct.
Also, Debian doesn't support Packages.bz2 any more, so I switched to Packages.gz.
Cheers,
Jason
