Hi,

I think you were a bit too quick with closing this bug report. I agree
that some people did hijack the report for other suggestions but I think
we have found the reason why we got different results with sbuild and
cowbuilder.

I have verified now that cowbuilder does not install gnupg by default
anymore, if you create a _new_ base chroot. However there is no current
mechanism in place that automatically removes packages like gnupg from
existing chroots on update. There aren't any warnings either.

Johannes Schauer explained at [1] how he did achieve that for sbuild. It
would be cool, if cowbuilder could do the same.

Regards,

Markus
