Wouldn't it be cool if the policy copygroups contained additional facilities
for specifying that a revision of a file which corresponds to a weekly or
monthly 'view' of a filesystem should be retained for an alternative length
of time? Expiration would have to get more intelligent (groans) so it
doesn't expire these 'views' of data until the specified time. Reclamation
etc would work as normal.

I'm going to submit this as a request through the usual channels. This means
it won't get done unless everybody hits them with it. Anyone else think this
change would be a good idea?
