Simple question:

With writeable CDROM drives around $700, has anybody considered setting up
their system from the Solaris CD, adding whatever software they need/want
to the machine and then backing the disk to WCDROM?  It would seem that if
data files are backed up at regular intervals to the standard backup
system, the pure system could be quickly recreated any time there was a
question about break-ins.  Maybe even on a regular basis.
