That sounds like sensible advice.

Disclaimer1: I'm making this up out of thin air.

If the device node is assigned at system boot, could you run a script from
your 'rc.local' that would identify the node by looking in '/proc', then
assign that value to some environmental variable? If you could then define
the mount point in '/etc/fstab' in terms of that environmental, you might
have what you want. (If you can't get a symbol expanded from inside
'/etc/fstab', you might use a trivial script or 'alias' to define a
device-specific command line mount.)
