I choose c) for the systems here, including the syncing into our normal package upgrade scripts, making sure that /boot/efi and /boot/efi2 are in sync after every package update. Code looks like this: if [ -d /boot/efi/EFI/debian/ -a -d /boot/efi2/EFI/debian/ ]; then echo 'Multiple UEFI ESP found' if ! diff -rq /boot/efi/EFI/debian/ /boot/efi2/EFI/debian/; then echo 'ESP differ, need to rsync' rsync -rv /boot/efi/EFI/debian/ /boot/efi2/EFI/debian/ fi fi Grüße, Sven. -- Sigmentation fault.
