Mika has rewritten the post-install script completely to load all the
modules by default (except the modules that are irrelevant to Debian
like anaconda or portage). That means that we are not looking at the
installed packages anymore, this was not really scalable and the fact
that it was not installing new modules when new .deb were installed
could be confusing for the user. We are however not re-enabling modules
that the user has explicitly disabled using semodule -d.
We are also upgrading the complete policy all the time now, which makes
selinux-policy-upgrade a bit useless. We could maybe add a debconf
question to allow the user to disabled this.

This as been more or less fixed by setting "expand-check=0"
in /etc/selinux/semanage.conf. semodule -B takes something like 10s to
run here on my laptop.

Indeed we should maybe also look at this and force a relabel if needed.
