mkosi automatically builds for the host distro which seems a much
better default to encourage since dnf won't be installed on any host
system that's not Fedora anyway.
$ meson build # configure the build
$ meson compile -C build # build it locally, see if everything compiles fine
$ meson test -C build # run some simple regression tests
-$ ln -s .mkosi/mkosi.fedora mkosi.default # Configure mkosi to build a fedora image
$ sudo mkosi # build a test image
$ sudo mkosi boot # boot up the test image
$ git add -p # interactively put together your patch
