Hi David,

The behavior shouldn't have changed.  You've provided just about all the 
relevant details in your email, so there isn't really anything I want to 
ask for more information.

Can I have you try setting /etc/sysconfig/init => SINGLE to 
/sbin/sulogin rebooting and setting it back to /sbin/sushell?  Perhaps 
something got 'stuck' wrong....

/sbin/sushell is a shell script, so can I have you verify its contents?  
Mine looks like:

#!/bin/bash

[ -z "$SUSHELL" ] && SUSHELL=/bin/bash

exec $SUSHELL
