After following up on Bryan McLellan's suggestion to read the manpage 
for udev,

http://www.linuxcommand.org/man_pages/udev8.html ,

I now think that this command may be responsible for assigning the 
device names. Actually, I think "may be" is weak, but my knowledge about 
this is slim to none.

I thought that udev only used the uuid name, which may not be unique 
(e.g. when I cloned my working drive), but Bryan pointed out that udev 
uses other pieces of information to uniquely identify drives.
