My "visions" go elsewhere:

The users who still need partition tables shall get theirs in a sane way
-- maybe as David Miller proposed, or just simple Sun-styled partition
tables (even though I don't think they're _much_ saner than PC partition

And the second thing is about your point one. We have two big raid arrays
divided into three racks. Here we have one logical disk divided into many
physical disks. If you want to know the constraints, call the controller
and ask for it. The rest is bogus -- why should I have a partition table?
Maybe divide the raid into smaller disks?!

That's it.
