Question is, is there anything worth protecting with ASLR or we don't care? I wanna say, we should randomize just in case, especially as it shouldn't be that expensive to do. Also, how does the whole EFI-in-the-kexec-ed-kernel work on ARM? Runtime services get mapped on-demand in the kexec-ed kernel too? -- Regards/Gruss, Boris.
