Functional, but it's a new filesystem with not as much time-tested
experience in the field.  Many Solaris system administrators are
electing to wait rather than immediately press it into service for
critical servers, electing to use Solaris's UFS instead.  I've heard a
few problems with ZFS recovering from data corruption, but not enough
to know whether it is a general trend (not that I track that kind of
stuff).  As a rule, enterprise system administrators that run PO
servers for thousands of users as a time are extremely conservative,
and for good reason.   

Of course, there's a big difference between those folks and people
using ZFS for their own personal development.
