Comment 31 for bug 1382511

>> So now we don't need to copy whole /var/log
But the whole copy made, and then subdir is deleted using utils.remove, right?
So It definitely give us ability to reduce resulting snapshot size, but doesn't changes free space requirements.
So snapshot may faill if we don't nave at least (2 * /var/log/ free space)

>Also I add fix which will remove old snapshots from environment and this will give as more space on the disk especially on environments which had a lot of snapshots.
I'm not sure about that because snapshots contains dump of nailgun postgres db and cobbler data.
When containers corrupted old snapshots saved us several times: we got db dump from snapshot and restored it.
