Hopefully, this list will one day be obsoleted by DEVFS, but for now
this is the current allocation of device major numbers.
For local use, you are encouraged to use the reserved numbers.
If you intend the driver to be available, send email to the
hackers@freebsd.org mailing list to see about having a number
reserved for you.
The most "complete" version of this will be the one in FreeBSD-current.
(see http://www.freebsd.org/ or from ftp://ftp.cdrom.com/pub/FreeBSD/)
