 A request from the Feb 2013 Amsterdam BIND 10 training:

 In the current Logging system (1.0.0) is is possible to have multiple
 loggers write to the same file. However, each logger requites its own
 "output-options", with "maxsize" and "maxvar" that can be different.

 BIND 9 solves this function better, by having the "channel" definition
 that is then connected to a "category". The current "logger"
 configurations are like the BIND 9 categories, with "hardwired" channels.

 It would be better to have the "output_options" separate from the loggers,
 and specify the output_option (maybe even named "channel") with name in
 the Logger
