Public bug reported:

Using BTRFS to allow snapshot rollback from version updates actually
worked... I updated from 14.04 to 14.10 on Nov 1st, and encountered a
problem, I saw that update-manager had taken a snapshot before
completing the update, but after rollback I found that the snapshot was
taken AFTER the 14.10 sources had been put in place.

Clearly the snapshot should be taken before changes are made to the
package configuration, or rollback will not be complete.
