This is my point. Your *system* regenerated eth1. My *installer* generated eth1.
When I install, I have set
language
keyboard
locale
and I have provided a USB stick with the tg3 and ipw2200 firmware.
Nothing else.
I might look around and find a /etc/udev/rules.d/70-persistent-net.rules
file, but persist it will not! The only thing that persists at this
stage is /target, and that's barely begun construction at this step
in the installation. I think fiddling at that point is beyond even
an "expert" install.
So what I want to know from deloptes (or anyone else) is:
Why does this system (and yours) default to eth1, and
How can it be changed *at this point in the install*, if it
really is just a "default".

Agreed. I could do all this, but it would gain me nothing as
eth1 works perfectly ok.
I have a suspicion that, at some time in the past, not every kernel's
ipw2200 module has worked properly (even with the firmware apparently
correctly loaded). However, I have no evidence, and it's water under
the bridge. It could have been finger trouble on my part.
Cheers,
David.
