OK... well, it's not remotely convenient.  I *really* do not want to go through all the places where I expect (a) to use eth0 or (b) recode stuff that expects an interface name to be [a-z]+[0-9]+.

It's a wonderful idea to stop the name changing if a new interface is added... but everybody knows what eth0 is, and p32p1 is not as obvious.  I can see that there is a problem if interface 'x' is expected to be eth0 when interface 'y' already has that name.  So starting off with some "real" names which are so hugely inconvenient that nobody would want to use them (say "mac-xx-xx-xx-xx-xx-xx") and then having a user accessible mapping to "effective" name would do the trick nicely.

I have found /etc/udev/rules.d/70-persistent-net.rules and told it:

ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*", ATTR{address}=="xx:...:xx", KERNEL=="eth*", NAME="eth0"

but dmseg still says:

... udev [494]: renamed network interface eth0 to p32p1

Does anyone know how I map the [494] back to whatever rule it is that does this renaming ?

Thanks,

Chris
