Code Review
This pull request effectively addresses the issue of bootupctl update failing in environments without block-backed root filesystems, such as ephemeral VMs using virtiofs. The core change to make get_devices() return an Option is well-implemented and propagated correctly to the callers, allowing them to gracefully skip the update. The addition of ci/ephemeral-test.sh is a great way to ensure this new behavior is tested. I have one main concern about the completeness of the fix regarding other components, which I've detailed in a specific comment.

In environments without block-backed boot filesystems (virtiofs in bcvk ephemeral, NFS root, ISO boot, etc.) there is no on-disk bootloader to manage. Previously the update path would fail because list_dev_current_root() bailed when it could not find a block device from /boot or /sysroot.

On Fedora 43 dnf is dnf5, and the copr subcommand is provided by the dnf5-plugins package rather than dnf-plugins-core. Without it the ephemeral CI job fails with: Unknown argument "copr" for command "dnf5". Install dnf5-plugins with a fallback (|| true) so it's a no-op on CentOS Stream 9 where that package doesn't exist.
