nfs-idmapd.service would report following error when stopped: Starting NFSv4 ID-name mapping service... rpc.idmapd[1198]: Setting log level to 0 Started NFSv4 ID-name mapping service. rpc.idmapd[1198]: exiting on signal 15 Stopping NFSv4 ID-name mapping service... nfs-idmapd.service: Main process exited, code=exited, status=1/FAILURE nfs-idmapd.service: Failed with result 'exit-code'. Stopped NFSv4 ID-name mapping service. commit 93e8f092(idmapd: Add graceful exit and resource cleanup) redirected SIGTERM, so when executing "systemctl stop nfs-idmapd", the main() of idmapd would running to tail to return, while it returned 1 which considered as error by systemd. So here just return 0 in main(). (cherry picked from commit 03a9b6b8ca77aa603d265289709eedf032278466)
