Clearly that would have been a capital idea. Here you are:

I _believe_ that it is, but I am new to reading udevinfo output.

I'd like to give the volume a static name so that I can reliably point
autofs at it. While I realize that I could simply use the entries in
/dev/disk, I find it difficult to maintain the mental mapping of names
to device, especially at a glance.
Also, being able to write effective udev rules would be a handy skill.
