freebsd-skq/stand/defaults/loader.conf

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