This does sound like an excellent idea, especially WRT SCSI disks.
If I have three SCSI disks at ID 0, 2 and 4, and I take out the disk with ID 2, /dev/sdc currently gets remapped to /dev/sdb, which is a Bad Thing.
This was discussed a while back on the linux-scs- mailing list, and I believe Eric Youngdale produced a package to handle some of this at boot time.
My idea for disks that support it would be to have the disk "name" based on either the serial number or a unique identifier stored on the disk. Then would could move disks around arbitrarily on channels and IDs without confusing the mounts.
