+=== Systemd services
+
+Use a snippet like the following to enable/disable the service during
+installation/deinstallation:
+
+----
+post_install()
+{
+        chkconfig --add rc.foobar
+        # On install (not upgrade), enable (but don't start) the
+        # units by default
+        systemctl enable foobar.service >/dev/null 2>&1
+}
+
+post_upgrade()
+{
+        # Reload init system configuration, to make systemd honour changed
+	# unit files
+        systemctl daemon-reload >/dev/null 2>&1
+        if [ `vercmp $2 4.4-5` -lt 0 ]; then
+                if chkconfig rc.foobar; then
+                        post_install
+                fi
+        fi
+}
+
+pre_remove()
+{
+        chkconfig --del rc.foobar
+        # On uninstall (not upgrade), disable and stop the units
+        systemctl --no-reload disable foobar.service >/dev/null 2>&1
+        systemctl stop foobar.service >/dev/null 2>&1
+}
+
+post_remove()
+{
+        # Reload init system configuration, to make systemd honour
+        # deleted unit files
+        systemctl daemon-reload >/dev/null 2>&1
