Currently Mer packages require systemd in the build phase to use the systemd macros. This may change.
Until then your spec/yaml should contain:
BuildRequires: systemd
System units should be installed to:
%{_unitdir}
In preparation for next version:
%define _userunitdir /usr/lib/systemd/user/
and install user units to:
%{_userunitdir}
Note that no units should ever be installed into /etc/ although the installation macros will create symlinks there.
Links should almost never be installed into systemd/system/*.wants ; instead use the [Install] section of the unit.
All the %preun %post and %postun macros must be provided.
The %preun macro is simply
%systemd_preun my.service
The %post macro
%systemd_post my.service
The %postun is typically
%systemd_postun_with_restart my.service
For services that don't support a restart (eg if clients have stateful connections) then use:
%systemd_postun
These macros support the systemd 'preset' for controlling service policy. This essentially decides whether services run automatically when installed. Packages *must not* install preset files - the vendor should provide these.
