OpenRC

Installation

# emerge baselayout openrc --oneshot

Configuration

Merge your configs first:

# etc-update

Create a new symlink for your eth0, else your network won't be available after reboot:

# cd /etc/init.d

# ln -s net.lo net.eth0

Now edit /etc/conf.d/net, you'll find your old config in /etc/conf.d/net.eth0 but note that the syntax has changed so don't copy & paste. To set eth0 to a static IP you'll need something like this:

File: /etc/conf.d/net

config_eth0="192.168.0.2 netmask 255.255.255.0 brd 192.168.0.255"
routes_eth0="default via 192.168.0.1"
