# 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
# 
###
