Well, the badness mentioned above is the swapping of what gets loaded
first from the testing branch to the upstream patches. In mm, sata
gets loaded before pata in libata land. In alan cox's patches it's the
reverse. This results in different device names for the same config
when switching between mm and release, which is bad, but is a problem
that can be overcome with the use of labels instead of device names.

Perhaps from a distribution standpoint, moving to a label method of
describing what gets mounted where would be best, rather than worrying
about scsi naming schemes or ide ones. Just think of the fun of a
system with multiple usb storage devices and such.
I'm just not sure if grub and the kernel "root=" parameter can handle it.
