> What would the -s flag of mdsetimage be used for ?

I think I got it:

If the root ramdisk and the image have the same size, it does not matter
whether you specify the -s option to mdsetimage or not.

If the root ramdisk is larger than the image, you need to specify the -s
option if you want to make it possible to extract (mdsetimage -x) the
image from the kernel at a later point. If you didn't use -s, i.e. you
didn't write the image size to the kernel, and then extract the image,
you get the image plus the difference between the root ramdisk and the
image size.
