Right. And actually Macs had Quantum do a vendor unique Mode Select
page at one point so that SCSI id could be reassigned- all drives would
be shipped at ID 0 I believe (the 'config' address) and then be reassigned
at startup to the next available. Very usable, albeit expensive in
terms of SCSI target space.

It's not that I'm against using labels- it just restricts you to
information that can be scribble on at random, while WWNs and VPD info
is more lack MAC addrs (assigned at manufacturing time) and are
preferrable.
