why not run the debconf command here? we already did 90% of the required
checks if we end up here:
1. system is EFI booted
2. removable entry on ESP exists
3: MISSING: `debconf show --db configdb grub-efi-amd64 grub-pc | grep
'force_efi_extra_removable'`
we just need to query debconf to see if action actually needs to be taken.
without that last step, this will now warn *for all LVM systems*, even
those that are properly set up..
if we want to go the extra mile, we could also check that the binaries
actually match what is currently installed package-wise, but that might
get complicated in the face of shim..
