TODO

The following classes are deprecated and should be removed:

- base::newsyslog::messages::sa
- base::newsyslog::messages::sa::override

The utility of these classes are somewhat questionable:

- base::newsyslog::disabled

  Can groups just not install base::newsyslog on servers that don't want
  it?  The problem was with other modules that assumed something would
  arrange for Package['newsyslog'] to be available and that install log
  rotation rules, but shouldn't those packages be separately ported to
  logrotate or the like and behave conditionally based on which is
  enabled?
