That is odd. I am never prompted for the root password for anything.
Maybe this is a policy difference between GNOME and KDE.

Again, in KDE, there is a prompt for MY password and it is only modal
as far as the pkexec command is concerned. I can open my password
manager before responding to the prompt (not that I need to, since it
wants my password -- not root's).
Anyway, until this discussion, I never knew there was a pkexec. I
note that pkexec will not operate correctly outside of my KDE session.
It prompts for my password from a terminal session and then fails with
$ pkexec ls

Of course, sudo will operate correctly without a desktop session. I
don't think I will be eager to use pkexec instead of sudo.
