But as I understand it, what kexec will do is start an entirely new, fresh kernel instance, throwing away all of the old state. Although it may be faster than rebooting, especially on expensive server hardware (we've got some boxes which seriously take 4 minutes from power-on to bootloader), it still has the same effect: you throw away all of your currently running programs and state. That's not what happens when you decide you want to run using other common Linux virtualization technologies, and for casual users, it's an impediment. sytoka: Yes, kexec was mentioned when I brought up the discussion.
