This webserver is designed for small, local deployments. It does not come with a default configuration file, nor should it. As this daemon is so lightweight, the idea is that you may have many specialized configuration files for different, specialized purposes. You may even have multiple instances running at once.

Other packages that need webserver support should Depends: this package, provide a configuration file in its own folder, and then configure launchd to start it on demand (much as you might with inetd). This type of configuration means no memory (and certainly no battery power) would be wasted when lighttpd is not in use.

In the future there will be another package that provides a "default" configuration: one that chooses some random folder on disk as "your website" (in /var/mobile/Media). This would be for true end users who would like to quickly throw files up on the net, served from their device..

Do not file bugs about the lack of a configuration file, this is correct.
