Welcome to Icon Disti GhostBSD.png /boot/defaults/loader.conf.
This page is in maintenance!
Please do not change this page without to contact the author or use Discussion!

Introduction

This is the content /boot/defaults/loader.conf of GhostBSD 20.01. with a wiki formatting.

Content

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.

$FreeBSD$
