SCSI disk names change when adding / removing devices.

[Naoki]

Ok, I understand that cheers, but I'm not having a problem with the 
ordering of the devices it's the ordering of the controllers.
I have two controllers.  The first, and LSI ( the internal ), and my 
newly added Adaptec.
The LSI is detected first by the Bios and the Adaptec second ( which is 
what I want ). So why would the adaptec be assigned sda and my internal 
disks get sdb ?

That's what's breaking things for me. Because my internal disks are no 
longer sda1/2/3 my kickstart build fails (or installs onto the external 
array which I really don't want).

Anything I could do here, I think it's the hardware being funny and 
presenting itself to the kernel in the wrong order perhaps?
