snapshots should be working again

[Ken Raeburn]

Our ftp server setup was drastically changed a while ago for security
reasons.  This included turning off NFS access to the spool area,
which broke my snapshot scripts.  I've finally found some time to work
on fixing them, and I think what I've got now should work.  (My
automated testing might still be broken, but the snapshot mechanism
should work.)

Please try out the new snapshots.
