Yeah linux is unfortunately one of the few unixes that does NOT have
device names that map directly to a scsi bus,id,lun of the device.  A
real shame and very odd given how ide is handled.  Of course I think
with devfs is did have such devices for scsi, although I don't know if
udev does.

On the other hand having sda be the first found disk is very handy for
booting from software raid1 if a drive fails.  It probably wouldn't be
to hard to work with even if it didn't though.
