RHEL ignores whatever permissions are in the inode of the symlink, and only
looks at the permissions set in the inode of the file the symlink points to.
The symlink is a complete reference to the file it points to.

You will see, in the case of a symlink, if you try and change the
permissions on it, you'll actually end up changing the permissions of the
file it points to.

The fun thing is, in the event of trying to remove/modify the symlink, it
will STILL only look at the permissions of the referenced file, which is why
even though a symlink has full permissions, only people with permissions to
remove/modify the referenced file are the ones that can remove/modify the
symlink.
