Here definitely is a bug in the file contexts.
The eaccelerator stuff in the default implementation is referencing /var/cache/php-eaccelerator...
The same more or less goes for amavis, the default implementation uses the name /etc/amavis.conf
which in reality is /etc/amavisd.conf (there is a d added to the name).
Question is how to activate such a change.?
Add a file to the contexts/files directory or add some lines to the existing context files.
