Read about cpio headers: there needs to be some way to specify
what foe path to link to, a search across a file system for a specific
inode is quite performance intensive, so the path to the file to be linked
to is included in the cpio payload.

Or compare the metadata with and without the hardline using —yaml. All the
metadata is displayed with —yaml.

You asked to understand why the *.rpm package was larger. One (or both)
