# TO DO
# Add removal of swap

# This script is *DESTRUCTIVE*
# This is how I build NEMS distros from scratch
# This is *NOT* meant to be run by users - please do not run it unless you understand clearly what you're doing.

# Some of the ideas in this process come from DietPi - https://github.com/Fourdee/DietPi/blob/master/PREP_SYSTEM_FOR_DIETPI.sh
