Ok, but from my understanding setting attributes on a hardlink changes the
attributes of the inode the hardlink is pointing to, like for "normal" files
which are technically hardlinks too. So changing attributes for n "objects"
pointing to the same inode is like changing the attributes n times for the
same object or is this wrong?
If you think attributes for hardlinks have to be restored as well, the fix
for src/findlib/attribs.c has to be redone. I can do so but I still
think.... ;)
