Moreover providing ordering by IDE driver has been nightmare to maintain and can't be done correctly for 100% weird cases.

So how much weird cases do we have?

Speaking from personal experience, _waay_ too many. On my old G4 which now serves as a fileserver, I have 5 IDE busses out of 3 controllers (Onboard ATA-66 with 2 busses, onboard ATA-33 with one bus, add-in PCI ATA-100 with 2 busses) There's a _config_ option to control probe order specific to the two Apple onboard interfaces, and it used to be (before udev) that option was a nightmare to ensure that my new kernel has the same probe order as the old one. Once you throw PCI hotplug into the mix, reliable probing order is impossible, and you should just use udev to dynamically assign names.


(surprisingly) the other way round, sda just happens to be the first disk
inserted (SCA, USB, etc.)

Which is much saner approach from developers' POV.

Developer... and about the user/admin? With a sparcbox (ran suse linux 7.3 the last time it was powered on - 2.4 kernel, no udev - don't complain :), replugging disks in put them at the end of the 'sd*' naming chain, effectively killing the features of hotplug the machine itself offered. (Oh, that OS starting with S.. managed it with the help of the behated/-loved c?d?t?s? scheme, but that's OT.)

Yeah, 2.4 was bad at hotplug, everybody knows that already. This is why the changes were made for 2.6 to add udev and hal and make it much saner.
