You're right, I meant '=rr' and it should have been in the reverse order.

Never mind, I was more talking to myself here. It's really specific to my case. In practice, we found that we need to use nfs to get the 'root_squash' permissions auto changing on the files. So everything will be done after boot with multiple nfs mounts without aufs. Thank you for your answers. It was great to get feedback really quickly. Regards, Gaëtan > J. R.
