Great question — answering as the UphillTech team:
ZFS On Linux (ZOL) has come a long way in the past year or so. The developers have claimed it is production-ready with its recent v0.6.1 release. I've been running ZOL at home (still a pretty heavy workload, though) for a while now and I've had no problems. A lot of other people stand by ZOL as well. That said, using ZOL as the root (or / ) partition is tricky. It is doable, although probably not worth your time. I believe that the Arch wiki has information about it. The easiest path for you to take (in my option) would be to install Ubuntu on a separate boot drive (or mirror), install ZOL (from source or from the PPA ), and simply zpool import your existing ZFS pool. Something to keep in...
