enhancement proposal upstream

For the upcoming Fedora 41 release, we are enabling composefs by default for boo…table container images of Fedora Atomic Desktops (not for the classic ostree ones). See: - https://fedoraproject.org/wiki/Changes/ComposefsAtomicCoreOSIoT - https://gitlab.com/fedora/ostree/sig/-/issues/35 It's enabled in the Rawhide/41 images from ci-test: https://gitlab.com/fedora/ostree/ci-test/-/blob/main/composefs.yaml?ref_type=heads Before we move people to composefs, we need them to have a BLS capable bootloader (i.e. an updated open), have BLS config enabled and then set `sudo ostree config set sysroot.bootloader none`. If some of those things are not set, you might end up with a completely unbootable system (i.e. no rollback either). See: - https://gitlab.com/fedora/ostree/sig/-/issues/35#note_1986555833 - https://discussion.fedoraproject.org/t/f41-change-proposal-enabling-composefs-by-default-for-atomic-desktops-coreos-and-iot-self-contained/123166/18 So this is tricky as we don't have a mechanism in Atomic Desktops like we do in Fedora CoreOS to force updates through a barrier releases that would validate all of those elements before updating to a composefs enabled image and setting the ostree repo config. If that ends up being too much for the F41 release, we can postpone it to F42 or dynamically disable it in a layer (needs an initramfs rebuild).
