As suggested more than once in the lists, drop -M from flags to mfs
for /tmp and /var. This makes the memory discs swap-backed instead
of malloc-backed. A swap-backed memory disc should not be worse
than a malloc-backed one in any scenario because it will start
touching swap only when needed. OTOH, a malloc-backed disc can
starve limited kernel resources and evenually crash the system.
Reflect the change in the rc.conf(5) manpage. Also stop telling
lies there about softupdates: it does not waste disc space, it
just can delay its freeing.
