[Bug 1921134] Re: SBAT shim 15.4 release

[Julian Andres Klode]

I don't see any relevant changes in the shim userspace bits in the focal
update, and I can't speak to what Oracle does or does not do with their
packages. Certainly trying to compile the modules and install them,
setting up MOK, during boot like that is not going to work.
