systemctl: include -M or -H arguments in the hint
https://github.com/systemd/systemd/issues/2431 Some newlines are added, but the output will still exceed 80 columns in many cases. The fallback for oom conditions is changed from "n/a" to something "<service>", and a similar pattern is used for the new code. This way we have a realistic fallback for oom, which seems nicer than making the whole function return an error code which would then have to be propagated. $ systemctl -M fedora-rawhide restart systemd-networkd.service Job for systemd-networkd.service failed because start of the service was attempted too often. See "systemctl -M fedora-rawhide status systemd-networkd.service" and "journalctl -M fedora-rawhide -xe" for details. To force a start use "systemctl -M fedora-rawhide reset-failed systemd-networkd.service" followed by "systemctl -M fedora-rawhide start systemd-networkd.service" again.
