# Base syslog support
##############################################################################
#
# This module uses rsyslog where possible otherwise syslog is used.
#
# The default rsyslog support preserves the use of /etc/syslog.conf.
# The two most common overrides to this function are to not use
# /etc/syslog.conf configuration and to not use the default configuration
# that writes to /var/log/messages.  For example:
#
#  class s_ldap::conf::syslog-dev inherits base::syslog {
#    Base::Syslog::Config::Rsyslog['/etc/rsyslog.conf'] {
#      use_syslog_conf => false,
#      use_default     => false,
#    }
#  }
#
# Notes:
# * The newsyslog service is responsible for ensuring the file permissions
#   for the /var/log/messages log file
# * When use_syslog_conf is set to false then the /etc/syslog.confg file
#   is still installed, but it is ignored.  The goal is to drop the file
#   at some point.
