[yast-devel] sle12 network config in linuxrc
As the latest linuxrc with the new network code mostly active accidentally
slipped into rc1, I better describe the changes now. :-)

== network config before sle12 ==

** These options are still available in sle12. **

If the repo location is a network url you either get a dhcp config or can
supply a static config, e.g.

hostip= gateway= nameserver=

This config is tried on every network interface in turn until it works.

If you don't have a network repo you can still get a network config by


Also, if you do an ssh or vnc installation, linuxrc knows you'll need a
network config.

The major drawback here is that you can only configure a single interface.

== network config in sle12 ==

That's why there is now the new 'ifcfg' option. The example above would look

static: ifcfg=*=,,,
dhcp: ifcfg=*=dhcp

The general syntax is


It will create ifcfg/ifroute files for all matching interfaces (dhcp) resp.
the first matching interface (static setup), then run 'wicked ifup all' and
if wicked managed to bring up at least one interface, assume that tings

ip_addr_list and namserver_list are space-separated lists, so don't forget
to quote the 'ifcfg' option value.

If you use a wildcard pattern, it is matched against all existing interfaces
and mac addresses; if you use just an interface name, a config is created
regardless whether the interface exists.

A wildcard pattern will never match 'lo'.

You can have several 'ifcfg' options, of course.


- more than one interface can be configured
- supports vlan setup (e.g. ifcfg=eth0.55=dhcp)
- can set arbitray ifcfg options (ifcfg=eth3=dhcp,STARTMODE=nfsroot)
- no trial-and-error on all interfaces

Note: the transition to the new code is WIP. You may find occasionally that linuxrc thinks the network is not configured even though it really is.
