 It would be a pity if people compared ZFS on FreeBSD vs UFS on FreeBSD
(using the installer's defaults) and came to the conclusion that "Mail
programs don't work on ZFS on FreeBSD, use UFS instead."  I think it's well
known that there are performance differences between ZFS and UFS, depending
on your workload.  If you choose defaults that cause there to be
correctness differences, that could be detrimental.
