SELinux policy currently doesn't allow nut_upsmon_t to write to fifo_file:systemd_logind_inhibit_var_run_t Reproducible: Always Steps to Reproduce: 1.Install/configure nut-client 2.Start nut-monitor 3.Run systemd-inhibit --list Actual Results: No upsmon sleep inhibitor is listed Expected Results: WHO UID USER PID COMM WHAT WHY > upsmon 57 nut 435457 upsmon sleep Careful handling of OS slee> Additional Information: Denial is: type=AVC msg=audit(1747088012.000:22345): avc: denied { write } for pid=1452 comm="upsmon" path="/run/systemd/inhibit/6237.ref" dev="tmpfs" ino=46602 scontext=system_u:system_r:nut_upsmon_t:s0 tcontext=system_u:object_r:systemd_logind_inhibit_var_run_t:s0 tclass=fifo_file permissive=0 Adding a module with the following rule allows upsmon to work correctly: allow nut_upsmon_t systemd_logind_inhibit_var_run_t:fifo_file write;
