You can add a %trigger script. Something like this, completely untested: %triggerun xe-linux-distribution < …old…version+1… if test -e /etc/rc.d/rc3.d/Snn-…; then # enable systemd service based on old status systemctl enable xe-linux-distribution.service fi Please note that for new packages, the general guidelines apply (https://docs.fedoraproject.org/en-US/packaging-guidelines/DefaultServices/) and services should be managed through presets. But keeping enablement state on upgrade is outside of the guidelines and a nice thing to do.
