Hi Andrea, Good to know about kexecboot. FWIW, recently we discussed the kexec/kdump with secureboot issue at Linux Plumbers and Greg KH suggested that it will be simpler if we implement a new system call which does the job of loading new kernel. Effectively that means reimplementing /sbin/kexec in kernel. This will also mean maintaining two code bases for some time and slowly deprecating one over a period of time. I will probably start with something small and post proof of concept patches for review and see how does that go. This is just heads up on what I am planning to do.
