SELinux is preventing /opt/ruby-enterprise-1.8.7-2011.03/lib/ruby/gems/1.8/gems/passenger-3.0.7/agents/PassengerWatchdog from using the 'chown' capabilities.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that PassengerWatchdog should have the chown capability by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep PassengerWatchd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

I think it is time for a new passenger policy which was created for Passenger3.

Robert,
I could send you a local policy for testing?

I wish I could help, however I tried to setup a policy already via the SELinux Troubleshooter and in the end reverted to the setup we had here before installing Passenger. If you know how to remove a recently added policy however, I could remove it and try the setup again (the server was trying to run Gitorious on Passenger).

Thank you for the prompt answer.
