As part of the move to logstash 2.0 we are relying on upstream packaging for logstash. This packaging replaces a lot of the micromanagement of users and groups and dirs that was done in puppet for logstash. This is great news because its less work for us but means that the log processors can't rely on puppet resources for those items and we don't actually want to install logstash package everywhere we run log processor daemons. Since the log processors don't need a logstash service running and actually don't need any of the logstash stuff at all decouple them completely and have the log processor daemons use their own user, group, log dir, config dir, etc. With this in place we can easily switch to using the logstash packages only where we actually need logstash to be running.
