Host system details

Fedora 37, podman 4.3.1, running via a coreos-assembler container image.

[root@fabcca39d680 /]# rpm-ostree status
error: This system was not booted via libostree; found container=oci environment variable.
Currently, most rpm-ostree commands only work on ostree-based host systems.

Running cosa build multiple times and comparing the resulting commits results in:

This adds 100MB on every rebuild. @cgwalters recommended to open a ticket here first, if this is not the correct place, please point me to the correct location.

The rpmdb issue is tracked over at rpm-software-management/rpm#2219

The initramfs...hmm, I think this may be fallout from the zstd change.
