No sir, I don’t like it. Not at all.

The default mod_passenger “this app wouldn’t start” page includes an external CSS file:

http://www.modrails.com/error_pages/1.0/error_page.css

which is odd, considering there’s a bunch of inline CSS. I guess it’s to include the images. . . but it also amounts to disclosing something unintentionally. Yuck.
