I have a fedora workstation pac connected to the living room tv, running some server duties in the house and playing games over streaming and on the tv it is connected to.
I want to forbid reboot/shutdown from the UI. I want only sudo in the terminal to be able to do that.
I’m no certain of the best way to do that. I cant go just hiding the options on a per UI basis as I’ll be playing whack-a-mole until I’m dead. Instead, Id like things like plasma and steam to understand they aren’t permitted to make that request, but if they try anyway, the OS just ignores them.

systemd-inhibit seems like the right place to look,
but I have a vague feeling that gnome can override it.https://www.freedesktop.org/software/systemd/man/latest/systemd-inhibit.html
Maybe with some tweaking itll be unoveridable except for root?
at least in my experience GNOME does not override systemd-inhibit but rather just silently fails the shutdown
Weird. I’m sure i have seen a popup saying “shutdown was inhibited” that let me force it. I’ll have a try later today
Edit: gnome gave me the prompt, and then silently failed to shutdown. So yeah, perfect for OP.
Uh keep in mind they could just unplug the computer. Software limits are good, but if they really want to shut it off, they’ll find a way.
Physical access is not the concern I’m focused on here.
They’re gonna tap the power button anyway.
Which you can set to be ignored. Besides, it’s not in the living room. It’s in the basement below it.
You’re barking up the wrong tree and fucking up your life by doing this.
Split the streaming/gaming duty to a different device that can be operated in the way the user expects.
Wherever you disconnect shutdown signals from will be relied upon by something down the road and you’ll end up with a weird messed up broken update when that happens.
