Problem Statement

I cant find a way to keep my custom Rails error page bodies under normal operation, but still customize the internal Passenger fatal error screen.

Solution

I want to easily change the contents of the following file

 $(passenger-config about resourcesdir)/templates/error_renderer/without_details/src/index.html.template

Proposed Solution

It would be nice if there was a configuration option something like error_renderer_template which would allow us to configure a custom error page.
