[Bug 6367] Re: Hard disk order changes when using docking station

[Scott James Remnant]

After doing a little bit of research, this problem is actually entirely unique to Ubuntu.

We find devices by walking the /sys/class, /sys/block and /sys/devices trees.

Upstream udev has settled on, instead, walking /sys/class, /sys/block and /sys/bus

The change from /devices to /bus means that rather than seeing the IDE controller as a child of the PCI Bridge, and thus logically before the internal IDE controller, it would see the IDE controller as a member of the PCI bus that appears later.

I'm not sure only a couple of weeks away from release is the right time to make such a major change to our hardware enumeration though -- we'll get this fix in edgy anyway when we resync with the upstream udev and kernel versions.
