#Run this script as your user, NOT root
#Note: BTRFS Setup is not included in this script. I highly recommend using encrypted ZFS instead: https://linsomniac.gitlab.io/post/2020-04-09-ubuntu-2004-encrypted-zfs/
#I also took some codes from https://www.ncsc.gov.uk/collection/end-user-device-security/platform-specific-guidance/ubuntu-18-04-lts as well
