[Soekris] Best way to install openbsd

[Christopher Vance]

My machines run 512MB CFs, and have base40 and etc40 installed.  No
subsetting - 512MB is quite big enough for a real install.  You don't
need X or games, though, right?

I used a USB CF card reader on another machine, and installed there in
the usual way before putting the CF in the Soekris.

I moved /var to /eph/var, and made an empty /var.

I changed /etc/fstab to mount root with noatime, to mount /tmp as an
mfs, and to mount /var as an mfs initialized from /eph/var.  I added a
line to /etc/rc.shutdown to rsync /var back to /eph/var.  This is
because I'm running named on the machine, and want to keep my
/var/named updates, although remaking via zone transfer on boot isn't
a big deal, and to preserve /var/log.
