Build an Arch Linux root filesystem image for testing libbpf in a virtual
machine.
The image is generated as a zstd-compressed tarball.
This must be run as root, as most of the installation is done in a chroot.

NAME name of generated image file (default:
libbpf-vmtest-rootfs-\$DATE.tar.zst)
Options:
-h display this help message and exit"
