# Builds either a recovery image (BigSur-recovery.img) or a full installer (BigSur-full.img) for Big Sur.
# To build the full installer you must run this on macOS.
# The recovery can be built on either macOS or Linux.
# For Ubuntu (or similar Linux distribution) you'll need to run this first to get the required packages:
# sudo apt install qemu-utils make
# For macOS you'll probably need to run xcode-select --install to get the commandline tools
