It seems that description of majors/minors there is absolutely irrelevant
to the freebsd device nodes. Devfs simply does not work this way anymore
for long time.

Moreover, you cannot create special node that would become a node used to
access device driver in the freebsd.

The only use that is left for mknod c|b is to create special nodes on
the filesystems exported by NFS for other un*xes.
