pkexec is a part of polkit, it's available on Linux / BSD. And it's default privileges authorize frontend.

That sounds like a good idea. However, as I just tried this command out, it failed to start any Qt application with the following errors:

qt.qpa.xcb: could not connect to display

After a little reseach, I found this post: https://askubuntu.com/questions/287845/how-to-configure-pkexec Apparently, we need to pass a few command line arguments to make it work. (And a quick test actually shows it working).

Do you know of any other pitfalls with pkexec that one should be aware of before using it here?

@Skycoder42 I am not sure about that, but I suggest you make the adminauthorization as a shared library.
