What is the structure of the products directory, e.g.:

  $ ls -l /usr/share/zope/Products

Note that I disagree with Debian's choice to put the entire instance
under '/var':  most of it is *not* runtime-modifiable.  Only the 'var'
subdirectory (and 'logs', if so configured) should be under '/var':  the
rest should be either under '/etc' (e.g., in '/etc/zope', for the
instance configuration) or under '/usr' or '/usr/share'.

A workaround would be to symlink the CMF products from their current
installation directory into $INSTANCE_HOME/Products:  this is in fact
the *preferred* mechanism within the Zope community.
