Today, after many years of hard work from many people,
ZFS for Linux finally entered Debian. The package status can be seen on
the package tracker for zfs-linux. and
the team status page. If you want to help out, please join us.
The source code is available via git on Alioth. It would also be great if you could help out with
the dkms package, as it is an important piece of the puzzle to get ZFS working.
