Comment 5 for bug 1917509

I have successfully tested these grub2 updates on groovy, focal, bionic, and xenial bare metal machines with efi + secure boot, as well as a bionic efi system with secure boot disabled. All worked and things like grub menus continued to work.

On trusty/esm with the grub packages from esm-infra-security-staging installed, the grub menu no longer displays on boot, but keypresses are registered by the menu system and the system will continue to boot if the grub timeout is allowed to occur. See bug 1917529.

Thanks.
