>Description:
if you mount a read-only filesystem on a mount point, you cannot
chmod it, you will get an error. for example:

# chmod g-r /DATA
chmod: /DATA: Read-only file system
#

the chmod should only be denied for files/subdirectories
inside the mount point, not the mount point itself.
	
>How-To-Repeat:
- mount a filesystem as read-only
- chmod the mount point
	
>Fix:
