I understand the underlying meaning of what you are saying...that the
/root directory (which contains the public key) should always be secure.

What I am asking...is....what is the mechanism which drives the enforcement of the permissions? In other words, what I am asking is
what is actually causing the ssh public key authentication to actually
become disabled when directory level permissions on /root are loosened
rather than tightened.... Stated anothery way... is it the unix operating system or is it the ssh application itself which causes public key authentication to fail? Thanks.
