Unable to bootc switch again after migrating silverblue to fedora-bootc

[Perpixel]

Hello, not sure if this is working as expected, but I'm trying to test migration from a rpm-ostree Silverblue system to bootc on a qemu vm before doing it to my own workstation.

• Installed Silverblue:40, layered bootc. - OK
• bootc switch quay.io/fedora/fedora-bootc:40 - OK
• bootc switch quay.io/fedora/fedora-bootc:41 - OK
• bootc switch --transport oci-archive /tmp/custom-fedora-bootc.tar.gz - Staged but gone on reboot
• bootc switch quay.io/fedora/fedora-bootc:42 - Staged but gone on reboot

My system seems now stuck with only 2 deployments of fedora-bootc 40 and 41.

The documentation is not super clear on the right path to take to make this transition, so maybe it's just me?

Thanks

Just did the same step again on a clean VM, and now it works... Only this time I started from Silverblue:41

I was able to repro this if anyone interested. On reboot it probably fail in the deployment and reboot because I got a grub selection screen.
