WORK IN PROGRESS
Problem:
Base system settings like the hostname or the domainname cannot be changed after installation
Because of the deep integration of services in UCS, the hostname and other relevant settings are initially configured at various places - it is therefore not sufficient to “just” change the hostname, for example - each occurence of the hostname has to be changed.
A clean new configuration will only be created automatically in a new installation.
If a new installation is unwished, all settings have to be made by hand.
