##!/bin/bash
## Node Configuration 1.0
## By: Taylor Oliver
## Date: 2017/09/05
##
## Reason:
##    Streamlined boot for beowulf cluster nodes to be followed by post-boot scripts that load only what's necessary.
##    cat initial_setup_script.sh | cut -c2- > uncommented_initial_setup_script.sh && chmod +x uncommented_initial_setup_script.sh && ./uncommented_initial_setup_script.sh
## Metrics:
##    systemd-analyze
##        Before:
##            Startup finished in 35.150s (kernel) + 2.613s (userspace) = 37.764s
##            graphical.target reached after 2.582s in userspace
##        After:
##            Startup finished in 4.224s (kernel) + 2.789s (userspace) = 7.013s
##            graphical.target reached after 2.763s in userspace
