Thank you for your post, David, helping me again.
I have modified some text when I committed the instructions to use
'ssh-askpass' and 'pkexec', at r12399, after what you wrote. However, I
did not want to use xterm. Please, remember that in my original post, I
wrote (full of misplaced words):

It took longer for me to get the other pkexec solution exactly because I
dislike when I need xterm to get something. Another time I used it was a
bit similar to what you propose, when I wanted to get
shutdown/reboot/logout from a menu, and created a script that used
xterm. Later, I learned a little more, and replaced by a x-dialog script
as was used by gparted-live, pmagic and systemrescuecd (IIRC).
Thank you again for your post, and hope you do not mind that I did not
include your solution in the commit.
