The case of a laptop with a single sealed "spindle" (and maybe an
optical drive) is easy. Among else, you have the following options:
- Let the distributor figure it out for you.
- Link the driver for the onboard SATA controller statically into
the kernel. Make all other SCSI low-level providers (e.g. usb-
storage) modular.
In other words, if SATA and USB and other disks are mixed up, let the
distributor deal with the mix-up. You only ever deal with device
aliases in /dev/disk/by-*/ or with an even higher-level representation
by the desktop environment. _Or_ you enforce that the built-in SATA
drive is always /dev/sda, by having this drive always added first.

Have a look at the udev scripts or at Doug's lsscsi. Or simply use
lsscsi like a blackbox.
