Oh --- and how is the system supposed to know which file it is supposed
to use when there are several?
I believe it uses the last used network. I have used this in the past
to connect work and home ethernet ports with different setups on my
laptop. I do not remember the details since it was about a year back.

Then how come that it has emptied out my /etc/resolv.conf though
resolving information is in the ifcfg-* files?
Maybe what you think is correct resolving information is not actually
correct? Or could be a regression bug? There are numerous
possibilities but it has worked for me in the past. At the moment I'm
at work and can't test, but if I have the time later today I'll try to
test and see if it still works as I described.

Yes there are DNS entries in my ifcfg-* files and networkmanager
nonetheless empties out resolv.conf. So I take it that it must have
some configuration of its own --- unless it yields random results under
some circumstances.
Could it be that there is some conflicting information that is confusing
NM? In anycase, if I find the time to do the tests I'll report back
with my findings.
