If you power off your machine frequently, you could miss the execution
of some snapshots.
This is more troublesome the more infrequently the snapshots are
triggered. For example, monthly snapshots only execute at exactly
midnight on the first day of the month. If you only have your
machine powered on at that time with probability 50%, then half the
snapshots won't be triggered.
This means that if you wanted to keep 3 monthly snapshots, then instead
of keeping 3 months' worth of snapshotted data as you expected, you would
end up with snapshots spanning back 6 months.
Adding the "Persistent = yes" option to auto-snapshot timer units makes
a missed snapshot execute when booting up the machine.
Otherwise, in certain cases, snapshots of infrequently-modified
filesystems can be kept for a much longer time than the user would
normally expect, and cause a large amount of extra disk space to be
consumed.
Also added flag to snapshot filesystems in parallel by default.
I've also added a configuration option for zfs-auto-snapshot flags, so
that the user can override them.
For example, the user may want to append --utc to the list of default
options, so that the snapshot names don't cause name conflicts or
apparent time reversals due to daylight savings or timezone changes.

APIchanges looks like we should be able to replace 2.5 by 2.6
without anything breaking (belongs to staging and needs some testing).
