# Install loader, kernel, and enough of userland to boot in QEMU and echo
# "Hello world." from init, as a very quick smoke test for CI. Uses QEMU's
# virtual FAT filesystem to avoid the need to create a disk image. While
# designed for CI automated testing, this script can also be run by hand as
# a quick smoke-test. The rootgen.sh and related scripts generate much more
# extensive tests for many combinations of boot env (ufs, zfs, geli, etc).
