See:

Now as Lennart is arguing here, running gedit as root is crack.  But
the problem is greatly exacerbated by systemd leaving XDG_RUNTIME_DIR as
the user, which causes the root-owned process to write to it,
leaving directories owned by root whch can't be deleted by the user.

But if say you happen to be logged in via ssh or a getty as well,
that broken dconf directory will persist until you log out everywhere,
and it will break logging in via gdm.

This can happen with just pure "pkexec" and a *non-X11* application
which wants to save transient per-uid state.
