Like in the thread above, I also have a line
dns_domain_lo="mynetwork"
in my /etc/conf.d/net file. It says nothing to me
and I do not remember how it got there.
But somewhere on Gentoo forum I have found the following
explanation: "If you only specify dns_domain_lo="foo" and
restart the lo interface it will put "domain foo" in /etc/resolv.conf
and remove everything else."
So, I guess I should try to remove that line from my /etc/conf.d/net file.
But why the system worked fine for about a year *with* this line then?

Everywhere above eth0 has been put instead of its udev "predictable" name.
Do you think that I need
carrier_timeout_eth0=20
somewhere in /etc/conf.d/net ?
Thank you.
