I upgraded my e1000 kernel modules and after upgrading e1000 the net.eth0 script stopped recogining the eth0 interface with the following error message:
ERROR: interface eth0 does not exist
Ensure that you have loaded the correct kernel module for you hardware
ERROR: net.eth0 failed to start


This is a bit odd since eth0 definitely exists. The output of ls /sys/class/net/ gives
eth0 eth1 eth2 eth3 lo sit0


Also I am able to bring up the eth0 interface manually by using ifconfig, and can see its properties using ethtool and "ip link".

Any ideas why net.eth0 is mis-behaving? I don't understand the net.eth0 script well enough to identify what it is using to detect the existence of the eth0 interface. This seems like a bug in the openrc scripts.


Thanks

I had the same issue some time ago and i did a bugreport about it.

https://forums.gentoo.org/viewtopic-t-978516-highlight-.html

The problem was, that net.lo was not reemerged if it was somehow touched. Be it timestamp, checksum or anything other. Take a look at https://bugs.gentoo.org/show_bug.cgi?id=506966

Sorry for the pre-emptive post. Seems like the problem is not with openrc, but my installation. During the kernel upgrade I ended up blowing some files /lib which pretty broke whole of openRC. Re-did the installation and things are fine now.
