>Description:
Create a directory on the root folder, for example ("/whatever").
Switch to user's home directory ("cd /usr/home/username") ... from now onwards, work in this directory:
Create a symbolic link from inside a user's home ("ln -s /whatever .")
Execute this: ("chown -R username:username whatever")
Try to delete it using ("rm whatever")... it will say it is a directory. It is still not deleted!
Then, try to delete using ("rm -r -f whatever/"), no errormessage, BUT It is still there!
Then, again, try the same thing ("rm whatever")... It is GONE, INCLUDING the original at "/whatever" !!!
