In case this helps anyone I recently finished setting up a Debian server
closely following Ezra’s excellent guidance @
I used newer libraries in some cases (and mysql 5.0) and everything
great until the end when lighttpd wouldn’t start. I finally figured out
that Lighty 1.4.9 has a problem working with rails out-of-the-box. See
ticket http://trac.lighttpd.net/trac/ticket/487 for more info.
Maybe this will help someone else… and thanks Ezra!
