I see how this happened: ~forever was just last November.

- /dev/MAKEDEV exists on the disk after original installation
- forget to cd /dev && sh MAKEDEV all
- on boot, /sbin/init creates mfs partition and mounts over /dev
- it then runs the disk's MAKEDEV to populate mfs
- after the first update where MAKEDEV changes, postinstall deletes
  the MAKEDEV that is on the disk, and writes the new one to mfs
- on reboot, there is no longer a MAKEDEV on the disk for /sbin/init to use.

no more mystery...
