Last year, I moved my backup server to ZFS storage. That's great. But
it's not so great that it runs Arch with its frequent updates.
Right now, I can't even build the ZFS module (actually, it's SPL)
because the build breaks with GCC 7. It looks like it's easy to fix
[0], but hey, that's my backup server, I don't want to run any
experiments there.
Hence, I'm now switching to Ubuntu 16.04. :/ I thought about using
FreeBSD, but for maximum compatibility with both ZFS on Linux and my
legacy Linux software RAID, I eventually chose Ubuntu.
