Here's a hack that worked okay for me (creates and populates a /var
memory file sys at boot)...

- on the compact flash, cp etc/rc.d/diskless etc/rc.d/diskless2
- Add 'dlv=1' after the 'dlv=`sysctl ...' line

The existing diskless rc scripts in 5.x are geared toward nfs diskless
clients.  I have yet to look in detail at creating an rc script that
is tailored for a read-only / & /usr that are local (e.g., on the
compact flash), but the above got me running.

Building yesterday's -current on 4.8 worked okay for me.
