Now if they were really smart they would require a CDRW and they would
simply erase the last session and then append a new session with the
updated /home each time.  Then as long as your data will fit on the
disc, you get about 1000 rewrites of the CD.  but I guess they don't do
last session erase given they want to support CDR.
