Install the sample content by running rpm as root with the correct RAILS_ENV for your setup.

RAILS_ENV="development" rpm -i --force http://www.avalonmediasystem.org/downloads/avalon-sample-content.noarch.rpm

If running a manual installation, a hard link needs to be created so that the rpm can find avalon in the '/var/www/avalon/current' directory.

Example:

ln -s /var/www/avalon/ /var/www/avalon/current
