Comment 11 for bug 1504657

to be a little more clear with the existing implementation it would be like:

config:
  core:
    service:
      systemd-timesyncd:
        disable: true
      rsyslog:
        disable: true
      ssh:
        disable: false
    systemd-timesyncd:
      timeserver: 123.456.7.89

i.e. the service management is already in its own global "service" category ...
if we want that more task based (all timesyncd bits in one group instead of global service mgmt) we need to change some things in the hook.
