Add initrd shell command #6

Closed JohnAZoidberg closed 3 years ago

JohnAZoidberg commented 3 years ago

The initrd kernel parameter of the Linux EFISTUB is deprecated. The preferred method is the EFISTUB invoking the LoadFile2 protocol with a specific GUID. There's already a UEFI shell command to do that: https://github.com/ardbiesheuvel/edk2/commit/ac8f3ddf03c4fcda186a42918a234733153e42eb
