Possible bad choice of words on my part - what I meant to say was this
- you *have* to configure udev under linux - perhaps write a udev rule
that says "if the device id is such-and-such, then make the device
accessible by this name". You don't need to do that under Solaris,
it's solved much more elegantly. At least, for self-identifying
devices.

I for one will be eagerly awaiting the answer to this question :)
