Bug#35691: dpkg: New package dependency: "affects"

Package: dpkg
Severity: wishlist

I'd like to propose a new dependancy type which could possibly be described
best with the keyword "affects". The problem behind this is that with slink,
many packages that register new mimetypes do not depend on mime-support,
and thus get configured before mime-support. Since the /etc/mailcap file is
not present at configuration time, they assume that mime-support is not
installed, and skip this step. Thus, about 50% of the available mimetypes
are not registered.

I would propose that these packages could "affect" mime-support. As soon as
something about the installation status of mime-support changed, the
postinst script could be called with appropriate arguments, and the script
would make sure the package is still registered properly. This would also
allow to rebuild the database if it got lost, by simply re-installing

BTW, the same goes for the documentation. Until doc-base (I believe) is
installed, install-docs simply ignores every request to register
