I've been looking at how kafka is packaged and the provided scripts for running it. There are a few things I want to improve: it should be easier to run in the foreground or background, convincing java to keep the executable bits set, and reasonable log4j defaults. There are also a few plain old bugs detailed in KAFKA-81 that need to be fixed.
If there are other things that would make the results of ./sbt package or release-zip more useful, or the bash scripts easier to work with, please let me know. Thanks, Chris Burroughs
