This is great...
(I hope you can hear the irony)

OK, so I removed the two udev rules (70-persistent-net and 80-net-name-slot) files, thinking if this is the way the "upstream devs" are going then I have to check it out.
After removing the udev-rules and rebooting I got my two new network interfaces called enp0s4 and enp0s5 (no idea what that is supposed to mean).
My next step was to replace eth0 with enp0s5 and eth1 with enp0s4 in /etc/conf.d(net and create two new links (net.lo -> net.enp0s[45]) in /etc/init.d
Now I could start the two network interfaces (/etc/init.d/net.enp0s[45] start).
BUT, as soon as I try to start  some service (sshd, ntpd, ...) that is using the network I get a lot of complains that eth0 and eth1 is not started (and can not be started) and the service wont start.
What have I missed???
