[pve-devel] [PATCH installer] grub: set debconf value to indicate --removable install

[Fabian Grünbichler]

else we risk that the fallback boot manager and the rest of the Grub components
in /boot run out of sync, which can break booting on systems that use that
fallback entry instead of the regular one..

this debconf variable is read by grub-efi-amd64 and shim(-signed) postinst
script, if set, `--force-extra-removable` gets passed to their grub-install
invocations.

Reproduced by installing using the 8.0 iso, switching over to grub-efi-amd64
and attempting to boot the fallback entry instead of the 'proxmox' one.

Setting the debconf value before installing grub-efi-amd64 makes it all work
as expected.
