OK - so obviously user 'root' owns RAILS_ROOT/config/environment.rb, you don't 
have a passenger_user setting in your apache configuration so Apache/passenger 
drops privileges and runs the web package as user nobody:nogroup

If you want to fix the permissions on public/system/dragonfly, then you should 
either:

- change the ownership of RAILS_ROOT/config/environment.rb
or
- set the passenger_user in your apache configuration

and that user would have to be given write permissions not only on 
RAILS_ROOT/public/system/dragonfly (recursively) but also RAILS_ROOT/log folder 
(recursively) and also RAILS_ROOT/public/system (recursively)
