rm d2/f1 --> leads to "operation not permitted" You are right about the permissions: if i do sudo chown -R fred2:users d1 everything works fine, i.e. rm d2/f1 (executed as fred) removes d2/f1, and after an umount, it d2/f1 is there again. What i really need is: user fred2 works on directory d2, where he sees the files from home. He can edit/delete/create any file on d2, but cannot do anything to home. After an unmount, home is untouched as it was before. Disadvantage of sudo chown -R fred2:users d1 as described above is, that - fred2 can delete/change files from home - fred2 can delete/change files from d1 Kernel is 3.2.0-45-generic-pae from ubuntu 12.04 standard installation, the dirs are on ext4.
