Details:

This is my /boot:

/boot/8cuj15uc.iso
/boot/System.map-genkernel-x86_64-3.10.9
/boot/System.map-genkernel-x86_64-3.9.6
/boot/grub2
/boot/initramfs-genkernel-x86_64-3.10.9
/boot/initramfs-genkernel-x86_64-3.9.6
/boot/kernel-genkernel-x86_64-3.10.9
/boot/kernel-genkernel-x86_64-3.9.6

grib2-mkconfig insisten on preferring the 3.9.6 kernel over the 3.10.9
version. Here is why -- the grub-mkconfig_lib contains a "
version_test_numeric" function which attempts to use numeric sort for version
comparisons. Unfortunately, the rest of the code passes the file names
including the "genkernel-x86_64-" prefix, and `sort -n` falls back to regular
string sort. However, using `sort -V` for "version" sort works, see the
attached patch.
