We want to test that config writings from YaST produces certain conflicts.

The implementation as now, contains a couple of yast modules that uses the 70-yast.conf. Some of them that we can use for automation during the installation is

• net.ipv4.ip_forward
• net.ipv4.tcp_syncookies

These settings are available in the yast2 network module.

Scope is limited to 64bit on SLES only for the start.

Potential Scenario:

1. Check that module writes settings properly in /etc/sysctl.d/70-yast.conf and not in /etc/sysctl.conf (using yast2 lan module with settings mentioned above)
2. Set conflicting settings in /etc/sysctl.conf, edit them in yast module verify that yast module reports it
3. Set conflicting setting in custom file, e.g. /etc/sysctl.d/90-custom.conf , edit them in yast module verify that yast module reports it

1. in case of conflict all the settings are discarded
