During the IoT compose there is a warning:
DEBUG util.py:445: warning: boot-location: "new" is deprecated, use boot-location: modules

From https://rpm-ostree.readthedocs.io/en/stable/manual/treefile/

• "new": A misnomer, this value is no longer "new". Kernel data goes in /usr/lib/ostree-boot in addition to /usr/lib/modules. This is the default; use it if you have a need to care about upgrading from very old versions of libostree.
• "modules": Kernel data goes just in /usr/lib/modules. Use this for new systems, and systems that don't need to be upgraded from very old libostree versions.
