Our Ubuntu Server 12.04 system has a remote NTFS filesystem mounted via Samba at /media/blarg.
One of our users had problems writing to the remote system, but not reading from it.
Since the auto-mount script we've set up has a different user (we'll call it sagaba) mounting the remote system, I figured I'd change the permissions for /media/blarg to 774 sagaba:sagaba, and make our user a member of the sagaba group, so he can go about his business.
Unfortunately, when I attempt this (even as root), I get a permission denied error.
chown: changing ownership of `/media/blarg': Permission denied
Does this have to do with root squashing? I can't understand how it would, since the mount point is a directory on the local system.
