Yeah, it is a nice feature, to calculate the module installation size by delta of the whole initrd size.
Could you include the sample output in the changelog?
Thanks.

Thanks.
What about files used by many modules, like shared libraries and tools? The output should be taken with a grain of salt.

This rough printing at least can help use measure the module install size which is not shared. It is the increased size directly caused by the specific module_install.
Shared libraries is not considered here. It's hard to measure the shared part.. Do you have any idea or suggestions?
