> In other words, "ada" isn't the problem here, it's that we all still think in terms of the 1980's when systems didn't autoconfigure and device names were important hints to system functionality.  That time has thankfully passed, and it's time for us to catch up.

If this is important for disk type devices, why not also for network
type devices? Why don't we all use ethX like Linux does?

Personally I *like* knowing something about the underlying type of
device and technology - but I can definitely see both sides of the
argument here.
