Is it possible for Ext4 file systems (or maybe another one understood by Linux) to assign different metadata (like modification time, owner, access rights) to several hard-links that refer to the same data. (I know that for the size this is impossible, of course).
Rationale: I want to create a simple de-duplicated archive. It can (and often will) happen, that files contain precisely the same data, but the metadata differ. My idea was to create a hard-link per file and then set the metadata accordingly. But changing one hard-link seems to also change the others. (Or maybe there's another solution to my problem?)
