So if i'm understanding this right:
Sachin's proposal fails when the machine has no machine creds.
The current implementation fails when the logged-in user's credentials
are expired.
Can the NFS client's logic test for those different cases, use the
appropriate creds for RENEW in their difference, and reduce the failure
case to their intersection?
