When composing, describing and implementing the operation just need the
code to query and set the Partition object directly containing the file
system, instead of the enclosing encryption mapping to make it work.
The operation details for setting a new UUID on an encrypted ext4 file
system become:
Set a new random UUID on [Encrypted] ext4 file system on /dev/sdb4
+ calibrate /dev/sdb4
+ Set UUID on /dev/mapper/sdb4_crypt to a new, random value
+ tune2fs -U random /dev/mapper/sdb4_crypt
tune2fs 1.41.12 (17-May-2010)
Also note the now documented rule in apply_operation_to_disk() which
says each operation must leave the status of the encryption mapping and
file system as it found it.
