[Buildroot] [PATCH v2 8/8] syslog-ng: add logging configuration file

[Carlos Santos <casantos@datacom.com.br>]

Provide a template to help users to customize syslog-ng without editting
the startup script. Mostly warn about options that must not be used.

This file is also useful as an example for init script authors.
