This brings up a question. How does systemd handle bringing up a bridge and attaching an ethernet connection? In BLFS we do: ONBOOT=yes IFACE=br0 SERVICE="bridge ipv4-static" # Space separated IP=192.168.0.22 GATEWAY=192.168.0.1 PREFIX=24 BROADCAST=192.168.0.255 CHECK_LINK=no # Don't check before bridge is created STP=no # Spanning tree protocol, default no INTERFACE_COMPONENTS="eth0" # Add to IFACE, space separated devices IP_FORWARD=true and the ifup, bridge, and ipv4-static scripts handle it. How is this done with systemd? -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
