Should SG2D upgrade its GRUB2
Assuming this project is still alive, will it upgrade to latest GRUB2? (at the moment is been at v2.12 for awhile)
The project is relying on most recent stable versions of Debian and Ubuntu Grub2 packages for their Secureboot support. Those packages are Grub 2.06. That's why we match the Grub2 source code to Grub 2.06.
I am open to explore, let's say Grub 2.12 if some of the distros out there actually use some Grub 2.12 commands and their grub.cfg boot entries cannot be properly booted into if you use Grub 2.06 for them.
Nobody has complained so far so I guess it's not a big deal.
I am curious to know if the rationale behind your issue is something different than just using the last version because it's the latest version.
