Thanks, that works, and also handles curiousity on the systems with
SecureBoot disabled (where mokutil doesn't).

Looking at my systems, looks like neither of my Thinkpads have the 2023
key yet (although the newest one is a BIOS version behind due to
power-management issues in the latest).  Those are my only systems with
SB enabled (due to still having factory Windows on there; I never use it
but keep it around "just in case").

A couple of systems I do find the new key on are a 5+ year old Gigabyte
motherboard and an Intel/ASUS NUC (both of which have had BIOS updates
released this year).

I'm not familiar with the intricacies of the signing; can a single shim
be signed by multiple keys?  And if so... will MS still sign with the
old key for a while once they start signing with the new key?
