the Peripheral Device Identity Problem; was Re(2): Copied ... assigns eth2 to only Ethernet adapter
Roy, Clifford & others,
This is not meant to offend anyone. Certainly
not to offend any system architect, software
author, package maintainer or other contributor.
Just for sake of discussion, interest and
understanding.

In "http://alsa.opensrc.org/MultipleCards#Multiple_devices" we find,
"... stop naming Alsa devices using numbers, and use the real name of devices."
These are instances of the Peripheral
Device Identity Problem. With
contemporary busses, the real identity
of a device is available to software.
Ambiguity can be avoided by using real
identity rather than a traditional name
such as card0 or eth2. An Ethernet device
has an Ethernet address which is available
to udev.
So Roy, you can take consolation in the
likelihood that the problem will be solved
in the not-too-distant future.
