However the<br>> rights system sits on top of the Linux system and root rights are by<br>> default blocked and as you fond out, you cannot extend the rights<br>> through su or sudo. Normally you keep the same usernames and<br>> user-groups names as in Linux, but they are a different thing linked to<br>> the Linux users and groups and you can give them totally different<br>> names. What I see as the main advantage is that you can assign rights<br>> through secondary groups. <br>> NFS mainly is the Linux rights system, but it only sees the primary<br>> group.<br>> Probably you could have achieved the same by creating a CIFS group<br>> with sufficient rights and add your CIFS user to it.<br>> </div><div><br></div><div>Once I added :</div><div><div><br></div><div> # media share on NAS4Free</div><div> 192.168.0.250:/mnt/media /media/media nfs defaults 0 0</div><div><br></div><div>to my /etc/fstab, and setup the NFS mount feature on my NAS to look at the same directory, my files in /media/media all worked just as you'd expect them to on any drive in Linux.
