kexec-chooser

kexec-chooser is a thin wrapper around the kexec tool. It looks in /boot for available kernel images and associated ramdisk images, and will make the appropriate kexec call to load these into memory, and then create a stamp file. On a reboot (init level 6), if the stamp file exists, "kexec -e" will be called to execute the loaded kernel (a "warm reboot") instead of rebooting the machine.
