If you read this and care about keeping your system maintainable, please change
the layout of the plugins structure of cacti. Due to the way a lot of plug-ins
are written (details in bug #681558) in combination with Debian policy, I can
not fix this in the package.

* Create a directory /usr/local/share/cacti/plugins:
  mkdir /usr/local/share/cacti/plugins
* Move all content of /usr/share/cacti/site/plugins to
  /usr/local/share/cacti/plugins
  mv /usr/share/cacti/site/plugins/* /usr/local/share/cacti/plugins/
* Remove the empty /usr/share/cacti/site/plugins directory
  rmdir /usr/share/cacti/site/plugins
* Create the following symlinks:
  ln -s /usr/local/share/cacti/plugins /usr/share/cacti/site/plugins
  ln -s /usr/share/cacti/site/include /usr/local/share/cacti/include
  ln -s /usr/share/cacti/site/lib /usr/local/share/cacti/lib
