  With /boot/extlinux/extlinux.conf containing:

    default 1
    timeout 50

    label 0
        Whatever chaining is required for MS
    label 1
        kernel old
    label 2
        kernel new

    extlinux -M 2 /boot/extlinux
make the system boot new kernel once, after which old kernel will
be used?
