You are quite right - most of what's in /var is expected to be
persistent.  In the case where /var/tmp is on a mfs, it's hard to
oblige.  On these same systems, I do have rc scripts that save parts
of /var (those listed in an rc.conf variable) for shutdown, and
populate those dirs (after /etc/rc.d/var does its mtree stuff) on
start up.
