machine-types/core refactoring to make it more flexible
Browse files Browse the repository at this point in the history 
- Initial part factored out in a separate template, core-init.pan, to allow
execution of site specific actions between this initial part and the core configuration
- Ability to delay some part of the configuration, like file systems, in case some site
information must be defined before
- Hook to configure time synchronisation according to site needs (ntp, chrony...)
- Template cleanup
