What happens if you run "systemctl -i poweroff" as unpriv user? Is that honoured, or does that fail?

[systemd-devel] weird systemd-inhibit behaviour
Hello I am trying out systemd-inhibit as follows (on Arch Linux systemd version 238.133-4) but things dont seem to be working as expected. So I would like to know if I am missing something or is there a bug? Note: Everything is commented in /etc/systemd/logind.conf and there is no logind.conf.d directory in /run, /etc or /usr paths. Case 1) Inside multi-user.target - logged in to local tty as root. # systemd-inhibit --what=handle-hibernate-key:handle-lid-switch:handle-power-key:handle-suspend-key:idle:sleep:shutdown sleep 300 & # systemd-inhibit --list Who: sleep 300 (UID 0/root, PID 2544/systemd-inhibit) What: shutdown:sleep:idle:handle-power-key:handle-suspend-key:handle-hibernate-key:handle-lid-switch Why: Unknown reason Mode: block ... $ echo switched to non-root user $ systemctl suspend Operation inhibited by "sleep 300" (PID 2544 "systemd-inhibit", user root), reason is "Unknown reason". Please retry operation after closing inhibitors and logging out other users. Alternatively, ignore inhibitors and users with 'systemctl suspend -i'. # echo back as root user # systemctl suspend # or halt or poweroff or reboot It goes ahead and performs the action even if I am not using -i (--ignore-inhibitors) switch. Documentation for -i (--ignore-inhibitors) states this: If any locks are taken, shutdown and sleep state requests will normally fail (regardless of whether privileged or not) and a list of active locks is printed. It clearly states - "privileged or not" - so even if I am running systemctl as root - it should not shutdown or sleep in above case. Case 2) Inside graphical.target - using KDE plasma - logged in as a non-root user. Same first command as in case 1). # logged into KDE as non-root user but command below run as root inside konsole # systemd-inhibit --what=handle-hibernate-key:handle-lid-switch:handle-power-key:handle-suspend-key:idle:sleep:shutdown sleep 300 & Now if I click KDE Menu-->Leave-->Suspend (Suspend to RAM) ... it blocks suspend and asks me for root password - stating that there is an inhibitor. But if I click KDE Menu-->Leave-->Shut Down ... it goes ahead and shuts down the machine. /usr/lib/sddm/sddm.conf.d/sddm.conf has these systemctl commands mentioned in it: HaltCommand=/usr/bin/systemctl poweroff RebootCommand=/usr/bin/systemctl reboot So I believe something is not right or I am doing something wrong in an unexpected way. Case 2) may be KDE related issue but case 1) should atleast have worked as expected. Can anyone else test?
