Rolling out composefs to existing users
We're planning to turn on composefs by default in Fedora 41:
- https://fedoraproject.org/wiki/Changes/ComposefsAtomicCoreOSIoT
- Atomic Desktops: fedora/ostree/sig#35
- CoreOS: https://github.com/coreos/fedora-coreos-tracker/issues/1718
- IoT: https://github.com/fedora-iot/iot-distro/issues/52
We should discuss any compatibility constraints and/or how careful we want to be with this rollout.
Basically, fill out https://fedoraproject.org/wiki/Changes/ComposefsAtomicCoreOSIoT#Upgrade/compatibility_impact, but also see e.g. https://github.com/coreos/fedora-coreos-tracker/issues/1718#issuecomment-2206850063.
