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.
