+1 for this feature request. Network, DNS, and SSL would be amazing for clevis pin tang too :)

+1 For this, I'm not too familiar with making bootloaders but willing to help with implementing this, probably would need some "where to start" guidance or resources but I can easily go from there.

This would simplify my system setup soooo much.

This is something I'm interested in doing.

I have a half-finished LUKS Windows driver already; once that's finished, all that should be needed would be a corresponding EFI driver.
