I recently installed the guardian-2.0-002.x86_64 tarball on a fresh
test installation and everything worked as expected. If you previously
installed the broken 002 tarball, there might be some permission issues
left - especially the "/var/ipfire/guardian/" folder requires
nobody:nobody as ownership.

This would be one of my next goals, if you have already a working
patch, please send it the usual way to this list.

Do you have any special reason why this should be done?
