i think if you look closely at the XO you'll see that this is
essentially already done, but the mechanism is slightly different
than it might have been in the past.  compare the output of "df"
with "df /var/log", for instance, and look in /etc/rwtab.

if you follow this through in rc.sysinit, you'll find that everything
mentioned in /etc/rwtab is mounted on tmpfs.
