And still there's the big elephant in the room that gets overlooked by
many Linux users who lovingly cherish and maintain old computers. Back
in the day, over 90% (number pulled from arse) computers had exactly 1
hard drive controller, which could hand a maximum of 4 hard drives, and
the method to reference those hard drives was fixed (primary and
secondary master/slave). Pretty simple to keep /dev notation in line.
But now that's completely different. Most Mobos have at least 2 hard
drive IO controllers, 3 or 4 buses, and the bios reference to each drive
is completely fluid, and can often get changed with no notice. Going
back to /dev is just not an option, and making it one on install is just
inviting a regression in terms of support and ease of use.
