Overview

Provides functionality for network AutoYaST client(s)

This currently shouldn't replace *::Import methods. In other words it is intended for functionality which cannot be handled in 2nd stage properly. Typically:

  • merging configuration provided by linuxrc means and AY profile together
  • target network service setup (to avoid need of restarting the service during 2nd stage) and all other stuff which could lead to the need of restarting the service (e.g. device renaming)

#configure_hosts ⇒ Object

Initializates /etc/hosts according AY profile

If the installer is running in 1st stage mode only, then the configuration is also written

def configure_hosts
  Host.Write(gui: false)
end

#configure_lan ⇒ Boolean

Writes the autoyast network configuration according to the already imported configuration

If the network was already written before the proposal it returns without touching it

Returns:

  • (Boolean) —

    true when written

Checks if the profile asks for keeping installation network configuration

Returns:
