  Yes.  But I think that people who actually want to use the Apache
 package(s) are aware of how to disable sites they don't want, so
 adding it in as a new file should be reasonable.

  OK.  I'd be happy to do that.

  That ties in with the a2enmod change above I guess.

  Agreed.  I think it is worth adding, because it provides a
 nice centralized place for this kind of setting.

  I'll do that, but I always feel that its a little piecemeal
 doing it that way, because there are disparate changes which
 must be taken together.

  Anyway I'll make some changes against the version of apache2
 in sid, and follow up on these bugs.

  I'll close the four we've agreed are obsolete tomorrow to give
 anybody else chance to object.
