can't log in after update

[Richard B. Pyne]

I started updating my lunar based server this morning and now cannot log 
get to being root except from booting in single user mode.

I can ssh in as a normal user (root ssh is disabled) but then su - just 
returns me to the normal user prompt as if nothing happened.  Trying to 
log in from the console goes nowhere, just return to the login prompt.

I have tried re-lining shadow and openssh, both of which build and 
install without error, but it has not helped.

lunar fix says everything is okay.

Any help on what to do will be greatly appreciated.
