My point was that UEFI did not change the fact that "you cannot have

useless nitpicking isn't helpful
Barking up the wrong tree isn't useful either. EFI is not the culprit.
but the root cause - cause and effect
What is written in the EFI partition on kernel update in Fedora ? In
Debian, the EFI partition is written only on grub package update or
when running grub-install.
and where do you think is the kernel-selection stored?
I already wrote I don't know anything about Fedora.
https://fedoraproject.org/wiki/Changes/BootLoaderSpecByDefault
I did not find any information about where the kernel-selection is
stored in this page.
in /efi/loader/entries/
[root@srv-rhsoft:~]$ ls /efi/loader/entries/
I guess /efi it the EFI partition mount point. Well then, any system
tool that populates this directory should be able to manage multiple EFI
partitions.
yeah, and some tools think they have to rewrite every snippet in that
dir no matter from which os-install
Not my point. My point is that if secondary EFI partitions are
updated only during the boot sequence then they will be out of sync
at the next boot following an update of the primary EFI partition
nobody is takling about update it during the boot sequence
Please re-read the thread.

quick rsync in the initramfs or boot sequence to sync EFIs, then

yeah, initramfs is fine becaus ethat's generated due kernel-install

after I expressed disagreement, you wrote:
these ARE adequate places
ok, my mistake: initramfs generation is fine because at that point
everything is already there, the initrd is locate don the EFI and when
that's finished is the point to sync a backup-ESP
* kernel-install generates initrd and boot entries
* kernel-install needs a drop-in to run a script
after it's finished
* that script can rsync /efi/ to /efi-bkp/ or whereever
you mount the ESP on the second drive
* case closed - the ESP on both drives have the same
content and it just works
for now you need to rsync manually
and that was my point
