After mounting it, I did sudo chown betom: mnt_fld cd mnt_fld ls -la drwx------ 16 betom wheel 512 Feb 11 12:07 . drwxr-x--- 50 betom betom 3072 Feb 11 11:47 .. [...] which looks ok to me.. but as soon as I unmount and mount again, it reverts to root:wheel it isn't the end of the world as I will be wrapping the mounting process with a script, but I just wonder what is the story....
