-#
-# This script runs a build script in a QEMU VM using the latest Arch Linux installation medium.
-# The build script is expected to create an './output' directory in the project's directory (when running in the VM) and
-# place any build artifacts there.
-# After the build script has finished this script will copy all artifacts to a (local) './output' directory and shutdown
-# the VM.
-#
-# Dependencies:
-# - coreutils
-# - curl
-# - libarchive
-# - qemu-headless
-# - util-linux
-#
-# Considered environment variables:
-# ARCHISO_COW_SPACE_SIZE: The amount of RAM to allocate for the copy-on-write space used by archiso (defaults to 1g -
-# see https://man.archlinux.org/man/tmpfs.5 for understood units)
-# ARCHITECTURE: A string to set the CPU architecture (defaults to x86_64)
-# BUILD_SCRIPT: A script that will be called on the host (defaults to ./build-inside-vm.sh)
-# BUILD_SCRIPT_ARGS: The arguments to BUILD_SCRIPT (as a space delimited list)
-# PACKAGE_LIST: A space delimited list of packages to install to the virtual machine
-# PACMAN_MIRROR: The pacman mirror to use (defaults to "https://mirror.pkgbuild.com")
-# QEMU_DISK_SIZE: A string given to fallocate to create a scratch disk to build in (defaults to 8G - see
-# https://man.archlinux.org/man/fallocate.1 for understood units)
-# QEMU_VM_MEMORY: The amount of RAM (in MiB) allocated for the QEMU virtual machine (defaults to 1024)
-# QEMU_LOGIN_TIMEOUT: The maximum time (in seconds) to wait for the initial prompt in the VM to appear (defaults to 60)
-# QEMU_PACKAGES_TIMEOUT: The maximum time (in seconds) to wait for output from pacman when installing packages (defaults
-# to 120)
-# QEMU_BUILD_TIMEOUT: The maximum time (in seconds) to wait for output from the build script (defaults to 1800)
-# QEMU_COPY_ARTIFACTS_TIMEOUT: The maximum time (in seconds) to wait for output from the action of copying the build
-# artifacts from the VM to a local directory (defaults to 60)
