Bug 467366 – after udev upgrade i get error: cannot start xxx as net.eth0 would not start

• Product: Gentoo Linux
• Status: RESOLVED TEST-REQUEST

[Description svrmarty 2013-04-26 17:15:29 UTC]

after i've migrated to udev 200 with renaming net.eth0 to enp6s0 two services won't start
one is named(bind), the other one is dhcpd

error: cannot start named as net.eth0 would not start
error: cannot start dhcpd as net.eth0 would not start

there is no more entry with eth0 in /etc/* 

and there is also no comment in migration wiki or some bugs about how to fix this 

Reproducible: Always

ok, there are several services which would not start with this error msg.
ssh, squid, samba and so on

Did you remove the rules in /etc/udev/ what ls /sys/class/net/ says?

[Comment 3 svrmarty 2013-04-26 17:36:01 UTC]

as you can see, all rules are gone

after searching  !! 2 hours !! i've found the solution

in  /etc/conf.d/netmount was one line active

rc_need="net"

after changing it to

#rc_need="net"

it works.

seems to be a big impact

Removing x86, because not a stabilization bug.

You may need to replace default by boot, but here's how to do it:

1. rc-update del net.eth0 default
2. rm /etc/init.d/net.eth0
3. ln -s /etc/init.d/net /etc/init.d/net.enp6s0
4. rc-update add net.enp6s0 default

That way the net dependency will be satisfied.
