Hmmm - yes - that would be *easy* to arrange.  I could even mount that
partition read-only.

That sync option sounds *very* interesting - I didn't know it existed.  Looking
at the other mount options, the 'noatime' option looks good too - that
disables the updating of the "last access time" for the file.  Since
nobody *ever* cares about that field, I could happily set that option and
save a bunch of disk accesses.
