tools/gen-user-data generates a cloud-init user-data file from a configuration directory. It is mostly useful to embed files in the user-data. tools/deploy-qemu uses above tool to make a user-data file and spins up a virtual machine with it. This is useful to locally run, test, and debug osbuild-composer. A simple user-data directory for running tests locally is included in tests/deploy-user-data. It expects a repository with osbuild-composer rpms to be served on the host's port 8000.
