Comment # 6 on bug 1182838 from Ladislav Slez���k

This is related to bug 1180954, YaST should not crash when when a requested
client is missing. I think it should just print a error and allow to continue.

BTW the firstboot.xml control file is rather a template, the vendor should
adjust it according to their needs. I.e. enable/disable the registration step
(and ensure the yast2-registration is installed).

We should remove that %{is_opensuse} macro from the spec file. IIRC that was
already requested in the past. If Leap inherits the same packages from SLES
then it does not work anyway.
