8c45add2c0 Fix broken cron scripts
I found that none of the daily, hourly, weekly or monthly snapshots were
being taken. When I looked into it I found that the scripts didn't
execute properly, because of the newly introduced check (9c6f065).

I'm not versed enough with POSIX to understand if there was some clever
intention with using exec than just calling which by it self, but it
works without exec so I removed it.

f2767ad43a zfs destroy will use -d for deferred destruction
I am working on a complimentary script that does log-shipping style replication to a backup volume for highly efficient incremental backups. This relies on "zfs send -R" and that the sets of snapshots existing on the source and backup destination overlap by at least one snapshot. I plan to use snapshot clones to place a "checkpoint" reservation on a snapshot that will be required for future backups.

In order to keep zfs-auto-snapshot from destroying a snapshot necessary for a future incremental backup replication stream, I will create an unmounted clone of that snapshot, and destroy any prior clones when the backup completes. 

Any snapshots destroyed by the zfs-auto-snapshot "zfs destroy -d" will be destroyed as the dependent clones are destroyed. Without the -d option, zfs-auto-snapshot would fail to destroy the old snapshot with a checkpoint clone, and it would persist until later snapshot jobs destroy it in subsequent runs. Since monthlies and weeklies are relatively infrequent, deferred destruction will reap the snapshots opportunistically as soon as the "checkpoint" clones are gone. Intermediate snapshots between the "checkpoint" reserved snapshots and the recent snapshots preserved by the zfs-auto-snapshot.sh will still be immediately destroyed.

Resolve this lintian error:

	E: zfs-auto-snapshot: bad-permissions-for-etc-cron.d-script etc/cron.d/zfs-auto-snapshot 0755 != 0644
	W: zfs-auto-snapshot: executable-not-elf-or-script etc/cron.d/zfs-auto-snapshot

This should also resolve a related failure on Arch Linux.

bf4e97b07d Add a switch for the fast zfs list invocation.
Implement a `--fast` switch that uses the optimized `zfs list`
invocation instead of the slower regular form.

If the optimized form is generally better, then use it as the
default and reverse the switch to `--slow` sometime later.

Use only name property for zfs list

Markus Heberling
b6fba51643 Use only name property for zfs list
zfs list is very slow if it needs to retrieve other properties than name. See zfsonlinux/zfs#450 for reference.

This change uses only the name of the snapshot and uses awk to extract the snapshot date from the name and sort to sort it:

1. get all snapshot names, sorted by name
2. use grep to filter out any snapshot, that isn't correctly prefixed (maybe a check for the correct date format could also be added here)
3. use awk to extract the date and put the date before the snapshot
4. use sort to reverse sort this, first by date, then by snapshot name
5. use awk to remove the date, so that just the snapshot name is left

This significally speeds it up on my system (/root/zfs-auto-snapshot is the changed one, running with -n to get only the times for snapshot retrieval):

cc9f1802ed Fix pool exclusions.
Use $ZPOOL_STATUS instead of $ZFS_STATUS for pool exclusions.

A mistaken variable name made the pool exclusion logic a no-op and
broke the --skip-scrub switch.
