Code:
ls -l /etc/gshadow
  • lrwxrwxrwx 1 root root 20 jan 22 2003 gshadow -> KNOPPIX/etc/gshadow


Code:
ls -l /etc/group
  • -rw--r--r-- 1 root root 701 oct 9 18:45 group


Code:
ls -l /KNOPPIX/etc/gshadow
  • -rw--r----- 1 root root 501 aug 17 13:57 gshadow


So it is a question of how to get the rights to do that.
