1# This is loader.conf - a file full of useful variables that you can
2# set to change the default load behavior of your system. You should
3# not edit this file! Put any overrides into one of the
4# loader_conf_files instead and you will be able to update these
5# defaults later without spamming your local configuration information.

7# All arguments must be in double quotes.
