Are you really expecting me to hard disable fast reboot on the basis
of "I don't understand what this does"?

We looked at it years ago and decided that the interaction with
firmware secureboot was fine since a fast-reboot is roughlt the same
as a kexec between host kernels. If you think that's wrong (it might
be) then provide an actual explanation as to why.
