########################
# What this script is:
#
# An automatic installer for Gentoo Stable with the following features:
# 1. BTRFS with Grub Snapshots
# 2. KDE Desktop
# 3. The ability to build a custom and deployable image onto any machine
# 4. Easily create a bootable USB drive
# 5. Automatic Partitioning
#
# INSTRUCTIONS
#
# For new disk installs, initialize the disk to setup partitions from the main menu.
#
# Before running the install, ensure that you have Internet access.
#
# Please be sure to change USER,USER_PASSWORD, and ROOT_PASSWORD strings in this file
#
# To install a new OS to a disk, run gentoo.sh and choose option 1 from the main menu
