The only time I can see this being relevant is if either the device numbers
match the device numbers of the OS you are trying to be compatible with
(unlikely) or the device directory is nfs mounted. Now, whilst this might make
it marginally easier to setup network booting I would have thought that the
Right Way to do this would be to have a set of 'n-tools' ported to the major
vendor OSes which translate the device numbers on the fly.
Given this I think that the best thing to do would be to pick the scheme which
seems the most sane. This is largely a question of how many major numbers we
need (people will always run out of minor numbers however many bits you give
I take it that as far as NFS is concerned this is all opaque.
