[pve-devel] [PATCH qemu-server v2 6/9] efi disk: distinguish between having only MS 2023 cert and also having Windows 2023 cert

[Fiona Ebner <f.ebner@proxmox.com>]

Like this, the need to enroll the Windows 2023 cert can easily be
detected and done for drives where the Microsoft 2023 cert was already
enrolled.

New in v2.
