This is a flawed example. The problem is that you're relying on names
assigned in an irregular fashion and it will happen on Solaris as well
if you move disks between controllers etc. The way to do this in the
modern world is to rely on persistent names. See /dev/disk/* and the
udev rules for stable network interface names.  Of course you can argue
that e.g. /dev/sda or /dev/hda should stay stable but I doubt you're
going to find much sympathy for such a point of view.
