  Yes, this makes sense.
  I need to think about it some more, but at first sight modifying
the setting in stage 1 is the right thing to do. I didn't do it in
the first place because I directly translated stage 1 from the
execline script, which didn't include ctrl-alt-del setting because
it's policy, and didn't think further. Thanks for the suggestion.
