Giving the different kernel configs and the different userspace
initramfs setup it is hard to get an uniform value for all distributions,
but we can have an interface/kconfig-option for them to provide a value like this patch
is doing. And it could be improved like Kairui said about some known
kernel added extra values later, probably some more improvements if
doable.

Thanks
