# 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
#
# %pre
# %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
# %service_del_postun_without_restart demo.service
#
# Note: the upstream variants are also available and are aliases to
# their SUSE counterparts. However for consistency the SUSE macros
# should be preferred unless the package is intended to be portable
# across multiple distributions based on RPM.
