FWIW:
Don't Use ZFS on Linux: Linus Torvalds - It's FOSS
Torvalds will not allow Linux kernel inclusion of ZFS support because of Oracle's position on ZFS licensure, this was important to us because we have only ZFS on Solaris 11/12 boxes. We did not want different files systems for production Linux servers - but that is what we got....ext4
How this plays out on a home desktop I cannot say exactly. I would recommend NOT using ZFS for Linux boot filesystems - as @neo said.

Hi All,
How worried is everyone about the Dirty Cow Linux exploit? Has anybody experienced attacks yet?
From the research I've done it seems that the exploit is "reliable" (that is it works nearly every time on vulverable systems) which is not good news.

netapp::snapshot
NetApp::Snapshot(3pm) User Contributed Perl Documentation NetApp::Snapshot(3pm)
NAME
NetApp::Snapshot -- OO class for creating and managing snapshots
SYNOPSIS
use NetApp::Filer;
use NetApp::Snapshot;
my $filer = NetApp::Filer->new( .... );
DESCRIPTION
This class encapsulates a single NetApp snapshot, and provides methods for querying information about the snapshot, as well as methods for
managing it.
METHODS
get_parent
Returns the NetApp::Aggregate or NetApp::Volume object for the aggregate or volume for which object is a snapshot.
get_name
Returns a string representing the name of the snapshot.
get_date
Returns the date the snapshot was created.
get_used
Returns the percentage of space used by snapshot.
get_total
Returns the percentage of total space used by the snapshot.
get_snapshot_deltas
Returns an array of NetApp::Snapshot:Delta objects, each representing a single delta for this snapshot.
get_reclaimable
Returns the amount of reclaimable space, if the snapshot is deleted. Note that experimentally, this command has a lot of failure
scenarios, most of which are reasonable (there are a lot of cases where you can't query this data). Therefore, unlike most of the methods
in this API, it doesn't raise a fatal exception if it can't query the information, it simply generates warnings.
rename( $newname )
Renames the snapshot to the specified name.
restore( %args )
This method is an interface to the "snap restore" command. The argument syntax is:
$snapshot->restore(
type => 'vol' | 'file', # Defaults to vol
from_path => $from_path,
to_path => $to_path,
);
The 'type' argument maps to the -t CLI argument, and the 'to_path' argument maps to the -r CLI argument. Refer to the na_snap(1) man page,
and the "snap restore" documentation for further information.
