That's horrible. What's wrong with:

 for IF in /sys/class/net/*
 do
 # ...
 done

I always forget about /sys; sorry.  You still need to drop lo,

I'm now working on etch FAI, and ran into a totally different set of
bugs.

-_-

As a side effect, I've come up with a more general (in the sense of
working with the older stuff), faster way of dealing with the
multiple ethernet thing.  It stops when any one NIC is done.
