This is a multiboot PC. Only one bootloader is necessary. It isn't Fedora on
this one. I noticed existence of /efi/ shortly after last dnf upgrade, looked
at its content, thought it must have been an errant backup of some kind, moved
the content elsewhere as just-in-case before removing it all, and sure enough,
no more booting possible from NVME until after restoring from the backup and
recreating the required EFI boot entry.
Why was/is the ESP mounted anywhere when there is/was no fstab entry for it?
Why does /efi/ exist?
I added a new noauto fstab entry for the ESP to a unique location not within
/boot/ and deleted /efi/, with the result that it stays unmounted, and /efi/
stays absent.
