Re: amd64: kernel aslr support

Is live-kernel update more viable with this approach?
Live kernel update is a much more complicated business, [...]

I didn't write that the bit about live-kernel updates, but it occurs to
me that it could have been intended to refer not to updating the kernel
without disturbing a running system but rather to something more along
the lines of...kexec(), I think it was?  Basically, make the kernel -
or, here, the prekern - play bootloader for a new kernel.  Reboot in
most senses without actually dropping back to the hardware's BIOS (or
moral equivalent, for non-peecees).

I think the real point is updating a running system without interrupting the
services it provides (apache etc). There is, I think, little interest in
pseudo-reboots via the prekern, except wanting a fast reboot - which is still
not really useful.
