Let's try to standardize a bit the RPM macros used for
installing/uninstalling services.
This only covers the non-SysV compat bits, since that tends to vary
widely between the various distros.
Usage:
Add %{?systemd_requires} to the header of the spec file. And then:
%post
%systemd_post foobar.service
%preun
%systemd_preun foobar.service
%postun
%systemd_postun foobar.service
And, instead of the latter, in case the service shall be restarted on updates:
%postun
%systemd_postun_restart foobar.service
