Thank you. Now, I will be aware of this issue and disabling hotplugging in this way will be the next thing I will try if the problem will not be solved by just removing dns_domain_lo="mynetwork" from my /etc/conf.d/net file. It is not because I am stubborn (though it may be :) but because I want to do changes step by step to identify the cause of the problem. P.S. As far as I know, I have only one network interface on this computer, eth0, not counting lo, of course. :) > During boot, you'll see something like 'processing events' and that's > when udev is automagically doing it's start.
