# This is a build script for OS image generation using mkosi (https://github.com/systemd/mkosi).
# Simply invoke "mkosi" in the project directory to build an OS image.

# If mkosi.builddir/ exists mkosi will set $BUILDDIR to it, let's then use it
# as out-of-tree build dir. Otherwise, let's make up our own builddir.
