It is best to use the volume UUID to identify a volume uniquely, not

Volume UUID: 39605337-AB61-48DF-81C9-348947666FB9

Thanks for the response, but I am actually aiming to get to the
UUIDs, but I need to do this over a range of different computers (550
of 6 different models.. and both those numbers will expand). Basically
I need to figure out what disk is in "Bay 1", so I can get ahold of
the volume UUID's for all of the volumes on that disk.
I have put together code that can lookup the prefix on the
DAMediaBSDName for individual "platform names" (ie: iMac8,1), and from
there figure out the "bay number" for the disk, and then I have
default code if I don't have information for that "platform
name" (there is a pattern, but lots of exceptions), but am really
looking for a solution that does not involve me collecting the
DAMediaBSDName for the bays on every single computer model by hand. An
ideal solution would be some API that I could use to find the "Bay
number" of a given DADiskRef.
Oh.. and by doing registering for another callback I have eliminated
the need to write out to fstab at all, but am still doing so so that I
am not fighting the automouner at every startup.
