# NOTE: This is needed to make sure we are using the correct set
#       of systemd unit files. The RPMs lay down defaults but
#       the install/upgrade may override them in /etc/systemd/system/.
# NOTE: We don't use the systemd module as some versions of the module
#       require a service to be part of the call.
