Hmm... well without breaking naming conventions i guess we could easily go
up to /dev/wd0z or the like ? ... or even wd0zz ... so thats not really
the issue... i guess one has to look at the encoding of the IOCTL to know
how big that field can be at a maximum... would like the 32 or so ... i
know this is also an arbitrary number, but it's a 2^^6 instead of a 2^^4
so wont give that much trouble i guess, but then maybe 2^^8 is favourable.
The only programs that need to be pached is the bootloader i guess... and
maybe the bootblock loader. For all architectures that is though ...
hmm... cant see the complexity of it now but it doest sound that

Can't really imagine what to put on a 100Gb disc ... but then i thought
that also of my 4.7 Gb and i got once to a point that it was full (!!)
