Modified files:
sys/conf majors
Log:
This file lies by saying 200-255 are reserved for local use, thus
implying that they aren't used for the rest of the system.
Fix the lies:
253 is used by mfs (bad MFS for not registering it).
254 is a magic cookie inside of the dev code in at least one place.
255 is -1 which is magic in a different way in the dev code.
So, that means that 200-252 are reserved for local users. A grep for
252 didn't turn anything up, so I'm assuming it and lower are safe.
And I thought I was being smart by allocating our local major numbers
from 254 on down. This caused very very odd problems that were hard
to track down: close not being called, sync failing at reboot, etc.
