Comment # 1 on bug 1208004 from Reinhard Max

This code block is not for fixing or converting existing installations, it is
for genrating needed keys in new installations. The chmod/chown are only run if
$KEYSFILE does not yet exist and they are run while the newly created file
still has its temporary name.

I don't see how a packaged script would change the situation, because the
conditions under which it needs to be run (installing the ntp package for the
first time on a newly installed system) won't change.

Please advice.
