By slot name or motherboard position? Not without custom udev rules,
at this point. The biggest issue is that disk devices you have actual
device nodes, so you can make as many /dev/disk/by-path or by-id or
by-label symlinks that you want, without affecting something that
wants to access it by another name.

Since network devices don't have actual backing device nodes, they
can only be accessed by a single name. Which makes grand unified
device naming schemes for network hard. (Not to mention that attempting
to get consistent motherboard or slot position out of BIOSes across
all manufacturers is a boatload of fun.)

.... wrong? It's not 'wrong', in the same way that tcsh isn't wrong if
you're using bash. If someone's logged in on the console, it will be
recorded that way.
