As of right now, even if you don't care about capability to take crash
dumps, it is highly recommended to still use traditional swap
partitions even if your system is otherwise fully ZFS. There are know
stability problems involving using a ZVOL as a swap device. These
issues are being worked on, but this is still the situation as of now.

9-CURRENT: the real crazyland
8-STABLE: a dev branch, from which 8.0 was tagged and eventually 8.1 will be
RELENG_8_0: 8.0-RELEASE + latest critical security and reliability
updates (8.0 is up to patchset #2, hence -p2)

Same line of thinking applies to 7-STABLE, 7.3-RELEASE and so on.
