Subject: [gentoo-user] rc_hotplug and udev network interface renaming

1 Hi!
2
3 I'm running into problems combining network device hotplugging and udev
4 network device renaming rules.
5
6 Everything on its own works well:
7
8 - I have a udev rule in /etc/udev/rules.d/... telling udev to rename an
9 ethernet device based on its MAC address from say eth_old to eth_new.
10 When I plug the device in its name it correctly changed by udev.
11
12 - I have
13
14 rc_hotplug="net.eth_old !net.*"
15
16 in /etc/rc.conf. When I plug in the device it is automatically started
17 and the dhcpcd client runs for it.
18
19 When I combine both by using
20
21 rc_hotplug="net.eth_new !net.*"
22
23 then the device is renamed but no hotplugging occurs. When I use
24
25 rc_hotplug="net.eth_old !net.*"
26
27 then OpenRC tries to start up eth_old but fails to do so, because it has
28 already been renamed to eth_new.
29
30 Am I missing something here? Any help?

32 Regards
