Network interface names

[Steffen Grunewald]

Hi,

thanks for the responses which may turn out to be helpful in some way (if it's
already too late to get hold of the old-style if names) - during a half-hearted
test, the grub cmdline trick did not work for me.

What still makes me curious is

If I run FAI sysinfo, I see eth0, ..., wlan0, etc., and dmesg.log doesn't
contain any "renamed to" strings, so this renaming must have been avoided
somehow, and it's the "how" I am still looking for. (I.e., was makes the 
NFSROOT special in this respect as it uses the default kernel?)

As long as the un-renamed if names are available witin FAI, it's simple to
create that rules file. The devil may be in the detail when it's required
to exist (I suspect there's some initrd magic?)...

Thanks again,
 Steffen
