It searches in /etc/bashburnrc, but the file's is located at /etc/bashburn/bashburnrc.
Confirming this for app-cdr/bashburn-2.1.1. Workaround: # ln -s /etc/bashburn/bashburnrc /etc/bashburnrc I don't see a reason why there needs to be an /etc/bashburn _directory_, the config is just one file and should thus live directly in /etc.
Fixed
