My primary system at home is setup this way - primarily because at the
time I built it (Nov 2008), I felt ZFS was a bit immature and wanted
to have src and obj on UFS so I could do a rebuild if I lost access to
ZFS for some reason.  My experience has been that the UFS root has
caused me far more headaches than the ZFS parts.  I've since done some
reconfiguration and plan to switch to ZFS root soon.

Based on my experiences at home, I converted my desktop at work to
pure ZFS.  The only issues I've run into have been programs that
extensively use mmap(2) - which is a known issue with ZFS.
