Version 5.x of <peeve>whatever-the-hell-DEC-unix-is-called-this-week</peeve>
assigns virtual names to physical disks based on the order in which
they are discovered.  Thus /dev/disk/dsk0 will always be /dev/disk/dsk0
no matter which bus, target, or LUN it ends up as.  This has some 
advantages.  (I'm also fond of some advfs functions like clone filesets,
easy fileset quotas within a domain, and multiple disks in a file domain.)
