This is super touchy, and here is what I did to make it happy and stable.

This does not address if UEFI decides to write to one of these mirrors. Someone else has a systemd unit to assemble with resync.

In the past, I used someone else’s bypass script, but this was cleaner, and works in 18 and 20 LTS.

### Filesystem / Mirror for EFI / UEFI booting:
mdadm raid 1, metadata 1.0
vfat filesystem for /boot/EFI

### Proper GRUB package
apt-get purge grub\*
apt-get install grub-efi
apt-get autoremove

### Settings that seem to not stick
dpkg-reconfigure -p low grub-efi-amd64
Update NVRAM variables to automatically boot into Debian? NO
echo "grub-pc grub2/update_nvram boolean false" | debconf-set-selections
echo "grub-pc grub-efi/install_devices multiselect /dev/md0" | debconf-set-selections

### Grub config
update-grub
grub-install --no-nvram /dev/md0

### UEFI boot list (variables)

This is where it complains that hags is not up.
Rebooting does not bring up hags.
Manually starting, and it wil die after 20 mins or so.
Very little logging.

EVERY time I try to mess with HA, it’s broken. It’s always something different. Such a pain. Truly, I don’t know why people do not just use their own scripts.
