For the purposes of system rollback: Provide the ability to create a snapshot of all thinly provisioned LVM2 volumes associated with FS mount points that are relevant to a yum transaction.

== Detailed description == Yum's fs-snapshot plugin already has support for LVM2's old snapshots. LVM2's new thinp snapshots offer much more performance and ease administration. It is desirable to have the life-cycle of snapshots that are created by yum's fs- snapshot plugin be managed by the snapper utility. As such it could be that the yum fs-snapshot plugin is extend to provide a wrapper around snapper for the creation of thinp based snapshots.

Is this actually useful if anaconda doesn't set up the system to use the thinp pool to begin with? (Because it doesn't.)
