Install Fedora-IoT-ostree-x86_64-39-20231010.0.iso. 2. Run "cat /etc/os-release" 3. View PRETTY_NAME field. Actual Results: PRETTY_NAME field shows "Fedora Linux 39.20231006.0 (IoT Edition Prerelease)". Expected Results: PRETTY_NAME field shows "Fedora Linux 39.20231010.0 (IoT Edition Prerelease)"
/etc/os-release is part of fedora-release package and it's created when the package is built. Hence, the values in os-release are relevant to the date of the last build of fedora-release, not to the date of production of an ostree ISO (which, I assume, happens more often).
