Granted but what I saw after the xCAT postscript run is an "empty" 
/etc/resolv.conf including however the first comment line "# Generated 
by NetworkManager". Thus my idea that it is indeed NM which wrote it.

And I don't think the initial resolv.conf (coming from dhcp/pxe) isn't 
correct...

I'll try to adapt the netboot image to include TRACE level. I'll keep 
you informed.

That makes sense (and could fully explain what I'm experiencing 
afterwards which is event without none, nothing gets overriden)...


Thanks
