Good work Dan. I'll save this thread for future reference.
As someone who has used lots of external drives in the past you might
want to do your mount by label or some sort of drive specific UUID and
not by /dev/sda1. What can happen over time is that you'll add a
second drive and because USB or 1394 often do device discovery order
by which drive spins up first two identical drives will come up in
random orders which switches your mounting around strangely.
I've had good luck just mounting by label without using udev but I've
wanted to figure this out. You've given me a nice start. thanks.
Cheers,
Mark
