Attempting to rebase from Rawhide to 41 results in an error. The rpm-ostree rebase finished without issue, but the 41 boot option does not appear in GRUB at startup. This is what shows in rpm-ostree status after booting:

I found this discussion, but I don’t think the same root cause is here, as the rawhide deployment has no overlays.

I’m going to rebase from 40 → 41, to see if this is isolated to just a rawhide → 41 downgrade.
