Comment 45 for bug 1865515

We're in a bit of a bind here, even if we do fix LP:1906379 and LP:1910600 there is no way for MAAS to fix existing deployments. Meaning unilaterally using "exit 1" will break existing deployments which users will have to manually fix.

Is it at all possible to create a grub.cfg which can detect if there is a UEFI local boot entry which is next? If so we could use "exit 1" if there is an entry and fall back onto the exiting grub.cfg if there isn't.
