Do we have to make this a popularity contest? Parallels is currently in beta with a ksplice like upgrade involving kexec ... basically you checkpoint the system to ram, kexec to the new kernel and restore the images from ram ... it can upgrade a new kernel in a matter of seconds (and unlike ksplice, it's the correct kernel and can move between major versions). Since all the components that do this are open source, we anticipate this will become a common way to maintain servers, so kexec will see even more use than it currently does. Can't we detect Macs from some of the UEFI strings at boot time and do the right thing with the boot switch (which can be overriden from the kernel command line if we get it wrong)?
