If something is going to be modified to understand this, I would like it to be vinum. Most of my uses for FCAL attached storage involve some form of volume management. This approach does, of course, bring up the notion of a /devfs directory that contains the real disk information and a set of links in /dev (or /dev/dsk) that map the common names to the right devices. One of the big wins of using links to do this is that moving the disks around won't change where they appear in the /dev/da[0..N] namespace.
