 Hi,

 shouldn't command line settings override the environment?
 Probably not only --frontend vs. DEBIAN_FRONTEND, but for other
 parameters as well.

This is the behavior in all programs I've seen so far.

 I just ran into a problem when I wanted to manually reconfigure a
 package in a pbuilder environment (which had
 DEBIAN_FRONTEND=noninteractive set, but I didn't recognize this at
 once). Even running
   dpkg-reconfigure --frontend foobar package
 just exited with 0. No questions were asked. No way to reconfigure even
 debconf. Every option given to --frontend was silently overridden by
 DEBIAN_FRONTEND.

AOL.  I just tried to change /bin/sh to dash in my pbuilder setup and
scratched my head why dpkg-reconfigure dash would not do anything,
even with the --frontend and --priority options.

 These environment variables are also not mentioned in the
 dpkg-reconfigure manpage, only in debconf(7) which is in a separate
 package debconf-doc.

And even debconf.7 does not mention that DEBIAN_FRONTEND overrides the
--frontend option, at last I found it in the Debian changelog.
