SamYaple 5b6716cee8 Use fstrim to prep the block device ... This cuts the image size down alot, esspecially if there were lots of small file deletes. The fstrim utility is in the util-linux package and should be on most all systems. fstrim also works with XFS, ext4, btrfs, etc prodiving the kernel is new enough. A reduction of 25% or more in size is common. Change-Id: I269b4416be450369616f9b8e030f84c30e329804		2016-03-13 16:24:59 +00:00
