I'm not supposed to admit that. ;)

OK so after firmware update the system unsurprisingly still boots, because it 
is apparently still 2025. But none of the certificates have changed. I guess 
they'll get around to it in the next 11 months?

Meanwhile I've (re)experienced a "feature" of my Lenovo firmware. Whereupon 
loading BIOS defaults and saving them, there are no more boot entries listed in 
the firmware boot menu. Not Windows. Not Fedora. Both have bootloaders found on 
the EFI System partition but apparently this firmware won't list them unless 
they're also found in efivars?  Upon choosing the nvme raw device (it doesn't 
list partitions) it boots... Windows.

../fedora/shimx64.efi

Windows recovery boot menu likewise won't list Fedora, I guess because it's not 
found in efivars. 

Track down a Fedora install USB stick, and I'm able to fix this with 
efibootmgr, but... what a swig of sour milk. I'd put this in the soft fail 
category of how these sorts of updates can go sideways.
