# 1. Create three (3) disk images:
#    - Installer: 1024mb
#    - Swap: 512mb
#    - NixOS: rest
#
# 2. Boot in rescue mode with:
#    - /dev/sda -> Installer
#    - /dev/sdb -> Swap
#    - /dev/sdc -> NixOS
#
# 3. Once booted into Finnix (step 2) pipe this script to sh:
#      iso=<nixos-64bit-iso-url>
#      update-ca-certificates
#      curl $url | dd of=/dev/sda
#
# 4. Install these dotfiles with
#      git clone https://github.com/hlissner/dotfiles ~/.dotfiles
#      ln -s ~/.dotfiles /etc/dotfiles
#      cd ~/.dotfiles
#      mk install-linode
#
# 4. Create a configuration profile:
#    - Kernel: GRUB 2
#    - /dev/sda -> NixOS
#    - /dev/sdb -> Swap
#    - Helpers: distro and auto network helpers = off
#
# 5. Reboot into profile.
