The unit files have no installation config (WantedBy=, RequiredBy=, Also=,
Alias= settings in the [Install] section, and DefaultInstance= for template
units). This means they are not meant to be enabled using systemctl.

Possible reasons for having this kind of units are:
��������� A unit may be statically enabled by being symlinked from another unit's
  .wants/ or .requires/ directory.
��������� A unit's purpose may be to act as a helper for some other unit which has
  a requirement dependency on it.
��������� A unit may be started when needed via activation (socket, path, timer,
  D-Bus, udev, scripted systemctl call, ...).
��������� In case of template units, the unit is meant to be enabled with some
  instance name specified.


so that doesn't actually work, because the service definition is missing
parts...
