I think I found a valid solution. OBSD is installed in the soekris box by means of PEX/DHCP/TFTP, so no problems with geometry mismatches as with the flashdist approach. Next copy /dev/MAKEDEV to /root (or whatever place that you like) and modidy /etc/rc around the line 200 (after the mount -a command group) ... mount_mfs -s 10000 swap /dev mount_mfs -s 1000 swap /tmp mount_mfs -s 1000 swap /var/log mount_mfs -s 1000 swap /var/run # add mfs mountpoints for other critical directories. cd /dev ; /root/MAKEDEV ramdisk wscons pty pf tun mount -o ro / ... ramdisk, wscons and pty seems to be minimal devices to get basic funcionality. pf permits run pf and tun permits openvpn to work.
