From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How do you disable machinectl entirely? [solved] (iusearchlinux.fyi)

I’m mostly interested in disabling the command to create a root shell ‘machinectl shell @root’. Attempting to ‘systemctl disable systemd-machined’ doesn’t work.

Edit:

After some more poking, it seems polkit is the way to do it. Create the file /etc/polkit-1/rules.d/10-deny-machinectl.rules and add the following

polkit.addRule(function(action, subject) {
   if (action.id.startsWith("org.freedesktop.machine1.")) {
         return polkit.Result.NO;
   }
});

The list of all actions you can filter on are in /usr/share/polkit-1/actions/org.freedesktop.machine1.policy

I didn't find a way to disable the command but in this discussion they seem to change it to request the root password:

I didn't even know about machinectl. Thank you

The worst is that if the ‘wheel’ group is empty, it will give a root shell to absolutely anyone.
