We went through this at the beginning of the year. IIRC the format you suggest was considered, but rejected for some reasons I don't fully recall just now. One of those reasons is that 'd' implies a disc, which is wrong: that field (whether we call it 'd' or 'u') addresses a LUN. You can have multiple discs per LUN. I think the plan was to have c0b0t0u0d0 for disc 0 on LUN 0 c0b0t0u0d1 for disc 1 on LUN 0 p? for partition ? on a disc
when you had a LUN with multiple discs. If you have only one disc, you just get: c0b0t0u0
Also, there are now too many people using it for these kinds of changes to be "painless". SCO will just have to change their system: we have the bigger market share ;-)
