I haven't seen this work and I don't think such snaphots can be relied
upon: /boot, /etc and /var are affected by installs as well
(especially in the cases where you would want to roll back); I don't
think anybody wants exactly the separation provided by the crude /usr
vs. rest that is provided by the /usr move.
And snapshots that can not be relied upon may be even worse than no
snapshots if they motivate users to skip creating proper backups.
