- Always attempt mfs dev if missing /dev/console
- Save and run both MAKEDEV and MAKEDEV.local
- After creating the mfs dev, mknod() and freopen() /dev/console.
- If MAKEDEV is missing do not fail out early, but still create the mfs,
/dev/console.
- If we hit any errors fail out to single user.
This change _only_ affects systems booting without /dev/console.
