[gentoo-dev] nameif in gentoo init?

[Kazutomo Yoshii]

Hi,

Some of my machines have two more network interfaces.
So I just wanted to use nameif like rh.

Is it possible to add nameif support to Gentoo init?

eth0ext   Link encap:Ethernet  HWaddr 00:20:ED:17:02:A7  
          inet addr:192.168.1.80  Bcast:192.168.1.255  Mask:255.255.255.0
          ....

eth1local Link encap:Ethernet  HWaddr 00:D0:B7:22:1B:47  
          inet addr:192.168.1.79  Bcast:192.168.1.255  Mask:255.255.255.0
          ....

I was not sure that gentoo has similar functionality.
So I just hacked my gentoo.
If there is another good way, please tell me.
I'm also not sure whether other service uses default 
name(eth[0-9]) or not.


Here is my hack (quiet simple :->)

1. (very) small fix to /etc/init.d/modules
   see modules.patch below 

2. write /etc/mactab like 

eth0extern   00:20:ED:17:02:A7  
eth1local    00:D0:B7:22:1B:47

* I think that integrating to /etc/init.d/modules is more better

3. re-edit /etc/conf.d/net like 
   (removed old eth0 setting)

iface_eth0extern="192.168.1.80 broadcast 192.168.1.255 netmask 255.255.255.0"
iface_eth1local="192.168.1.79 broadcast 192.168.1.255 netmask 255.255.255.0"
gateway="eth0extern/192.168.1.111"

4. changed net.*

# rc-update del net.eth0
# cd /etc/init.d/
# mv net.eth0 net.eth0extern  (*1)
# ln -s net.eth0extern net.ext1local
# rc-update add net.eth0extern
# rc-update add net.eth0local

*1 : I guess this is not good idea for gentoo. 
     next baselayout update writes net.eth0 again

5. rebooting
