Comment # 62 on bug 1226122 from Mario Guzman

Martin, my best answers:

What I may have not made clear since I didn’t think it would make a difference
is that I use Refind and Refind Plus. Some info on refind: The original
(upstream) refind information is at:
https://www.rodsbooks.com/refind/

I use it to install refind plus which greatly enhances refind:
https://github.com/dakanji/RefindPlus

The license info should be in those websites. Years ago I entered an Opensuse
enhancement to include refind but didn’t think it would go anywhere. Was not
really needed anyway.

The Refind and Refind Plus maintainers was not aware of sdboot, I pointed both
of them to this issue. But probably nothing will happen unless needed to.

Q: can rEFInd boot openSUSE snapshots? If yes, how does it work? 
I am sure the answer is no, even though macOS has bootable snapshots. But I am
assuming based on not being info about snapshots in refind.

Q: Does reEFInd support secure boot and any kind of preboot measurement using
the TPM or other hardware?
Yes, see here: https://www.rodsbooks.com/refind/secureboot.html


Alberto, my best answers:
Yes only needed for Tumbleweed since it is most likely used for development on
multi boot systems.

For your last question, if I set TW to not install a boot manager it installs
nothing and leaves /boot empty. However, if during install I got into software
section and check suse-module-tools-scriptlets, no boot manager is installed
but /boot is properly populated to allow booting. Same as it always had.

Thank you both for taking a serious interest in this delima.
