Yes, from vi or whatever, you *can* save it, if you ask for force. And if you're not root, then you might have to ^Z out, chmod +r, then fg and then you can write it.

Or you might have opened it in view, rather than vi, which is the read-only mode; that still lets you write, but you *always* have to use force in that case.
