At the risk of sounding obtuse while asking for more help, I can work
out the rsync or dump part, but the rest I don't get. The
mountcritremote essentially just does a mount -a -t ..., yes? To
insert a few mdmfs commands followed by rsync commands, for example,
would require re-writing most the script. Is there a better place to
The reason I ask is that some time ago I had a look at nanobsd which
is designed to run on RO flash media. The /var and /tmp directories
are created as memory devices that supposedly get re-populated from a
/cfg directory at boot.
The /usr/src/tools/tools/nanobsd/nanobsd.sh setup script has a
function named setup_nanobsd_etc. Essentially, it writes out an
/etc/fstab file and does a 'touch /etc/diskless'. Unless there's
magic that happens behind the scenes with that /etc/diskless file, I
don't see how anything gets re-populated.
Put simply, I'm stuck somewhere between that script and your
suggestions thus far.
