There's a thread here:
https://github.com/zfsonlinux/zfs/issues/170 (I'm posting as
...Which implies that the hold-up (from a zfs-linux perspective) is the
lack of richacls support in the mainstream kernel at the moment. (E.g.
OpenSuse supports richacls out of the box, few other distros have included
the patches yet). Richacls should neatly sidestep the CDDL/GPL problem.

I"m still trying to fully understand the break(s) in the chain between
non-solaris/illumos Samba/CIFS and ZFS. Getting there slowly.

My medium term aim is a linux-based appliance that'll run on generic
hardware (even more generic than Illumos allows) with a ZFS filestore and
AD domain controller functionality, without having to do heavy duty
virtualisation and run disparate environment (e.g. running a linux Samba 4
DC as a KVM DomU under an Openindiana Dom0; way too complex).
