[Pkg-cacti-maint] Bug#681558: plug-ins in /usr/local/share don't find include files in ../include

Hi all,

This morning I filed bug 681558 [1] against my co-maintained package
cacti. When I was filing it, I was under the impression that the
solution would be simple, creating a soft-link from
/usr/local/share/cacti/include -> /usr/share/cacti/site/include. Before
I starting implementing it I decided to have a look at the policy about
such things, but unfortunately, unless I am much mistaken, this is not
allowed (section 9.1.2) [2].

So my question is how to deal with the following problem. Since cacti
0.8.8, the package supports plug-in architecture. This means that the
system administrator can add plug-ins to his installation to enhance the
functionality of cacti. As cacti is installed in /usr/share/cacti, and
the administrator is not supposed to add site specific things there, I
decided to let the admin put his plug-ins in
/usr/local/share/cacti/plugins and soft-link
/usr/share/cacti/site/plugins to that location. The bug I filed [1], is
about how this fails as some (or all, I have not tested yet), assume
that they are installed in a sub-directory of the main cacti
installation (including things like ../include/auth.php). I already
requested [3] upstream to allow for a system where the plugin directory
can be configured and I assume these kind of problems will, if accepted,
go away automatically. But until then, should I just consider plug-ins
that do this broken, and write in README.Debian that admins could create
a soft-link themselves (after I confirm that this really solves the
issue), or are there other possibilities that I have not thought of so far?

Are there other packages that have similar demands or problems?

Kind regards,
