It doesn't really help you when your data is modified by the update.
example:
installed: foo-1.0
data format: user:group:data:index:key
update: foo-1.2
data is migrated forward from the old format to the new one, new format is
stored in the same file but is:
user:group,group,group,group:data:data:data:index
(obviously I'm just making up the data format :)
how do you roll back and not lose access to the data in that file?
