Bug#1135137: Acknowledgement (upgrade-reports: Bookworm -> Trixie mdadm raid EFI not updated on both disks)

[Thorsten Behrens]

To end my testing, I did an 11->12 upgrade, which confirms it. There also only /boot/efi is updated. There also I can end up with FS0: as the old, not updated EFI entry.

And, because it's still grub 2.06, I can boot from it

Debian 11->12 upgrade. Confirmed /boot/efi only was updated

```
$ strings /mnt/second-efi/EFI/debian/grubx64.efi | grep -i grub | tail -6
        source $prefix/grub.cfg
        source $cmdpath/grub.cfg
normal (memdisk)/grub.cfg

&Debian Secure Boot Signer 2022 - grub20

$ strings /boot/efi/EFI/debian/grubx64.efi | grep -i grub | tail -6

```

Old:
```
~$ ls -l /mnt/second-efi/EFI/debian/grubx64.efi
-rwxr-xr-x 1 root root 4150720 Apr 28 12:43 /mnt/second-efi/EFI/debian/grubx64.efi
```

New:
```
~$ ls -l /boot/efi/EFI/debian/grubx64.efi
-rwxr-xr-x 1 root root 4199872 Apr 28 13:27 /boot/efi/EFI/debian/grubx64.efi
```

Reboot into BIOS and choose EFI shell, `sudo systemctl reboot --firmware-setup`

FS0: Old, verified by size of grubx64.efi
FS1: New, verified by size of grubx64.efi

FS0:
cd EFI
cd debian
shimx64.efi

Boots without issue

I know what to do as a workaround. Upgrade the second EFI partition.

What to do on the Debian side, that I have not a lot of input to, other than the previous idea to call this out in Release Notes.

Kind Regards
Thorsten
