+ Use rc.subr(8) features properly.
+ Do the whole job of obliterating /tmp contents in find(1).
+ Leave lost+found and quota.{user,group} in /tmp only if root-owned.
+ Make the overall structure clearer by first removing the X dirs
(perhaps along with the rest of /tmp) and then re-creating them.
+ Use "find -exec rm -rf {} +" for efficiency: each rm instance gets
a chance to kill as much files in /tmp as ARG_MAX permits.
