I could have offered that advice without being facetious, Matthew. ;-)
If you have adequate RAM and can mount a mfs for /var, symlink
/tmp->/var/tmp, that works. I have some rc scripts that periodically mount
a partition r/w and save the state of things in /var that I want to
And if you can't mount it read-only, mount it rw,noatime. Updating access
time causes many, many writes.
