	# These commands create and enter a aarch64 user space on x86_64 Debian/Ubuntu.
	# Expects qemu-aarch64-static to be installed and registered for the aarch64 binfmt on the host, see e.g.: https://codepyre.com/2019/12/arming-yourself/

	mkdir -p /tmp/chroot ; mount tmpfs -t tmpfs /tmp/chroot # (tmpfs is optional)
	debootstrap --arch=arm64 $(lsb_release --short --codename) /tmp/chroot # install aarch4 user space of host's distro

	# copy qemu to where it's registered as binfmt in the kernel (and since it is statically linked, copying a single file is sufficient)
	mkdir -p /tmp/chroot/$(dirname $(which qemu-aarch64-static))
	cp -a {/,/tmp/chroot/}$(which qemu-aarch64-static)
