It's not the same.

SSTATE and DL_DIR are on an nfs export anyhow and this works.

The problem here is with TMP dir (and an nfs server with a funny
underlying filesystem like UFS) and hard links.

In theory yes, in practice you will find out that if you build something
like core-image-sato-sdk "cp -al" is not the only place which creates
hard links.
