You didn't look at them. The first one changes a path to adapt to Homebrew directories structure (to make a script work) so it'll be rejected. Maybe there is another way to make it work using environment variables or by creating a libexec directory in the existing lib exec directory (not really nice). Other patches are just providing default sample configuration files. I can remove them but users will have to change them manually to launch the process (it's what is done for hadoop formula)
Configuration files are empty per default. It's just to make life easier to others for configuration files.
