ZFS root on single SSD?

The big question is what availability do you need on this server? As its a
home system I guess not as much as say an enterprise one. Therefore I would
imagine all the benefits of manageability that come with zfs will out weigh
the downside, even if running on a single volume. Boot environments are a
really big thing to safe guard yourself during upgrade time. Although in
theory you could do something with ufs its never going to be as good as
with zfs. Also remember mirroring isnt backup, mirroring is about
availability. Therefore live with a single drive, but backup the contents
