[systemd-devel] RPM macros for systemd : latest version

[Frederic Crozat]

Hi all,

we've been doing another round of changes to the RPM macros for systemd.
It is mostly to handle :
- migration from sysvinit (using Fedora scripts, but not relying on
triggers, because they don't play very will with OBS)
- presets (systemctl preset is called automatically)

# RPM macros for packages installing systemd unit files
#
###
#
# When a package install systemd unit files, it should use the following macros:
#
# add %systemd_requires in the specfile
#
# %post
# %service_add_pre demo.service demo1.service
#
# %post
# %service_add_post demo.service demo1.service
#
# %preun
# %service_del_preun demo.service
#
# %postun
# %service_del_postun demo.service
#
