Excellent, I do run bind, and I am familiar with the rndc key.  So the 
procedure that should work properly for 4.3 to 4.4 update is:

yum upgrade python-sqlite
yum upgrade sqllite
yum upgrade yum
yum clean all
yum update
massage bind rndc keys/files as required so keys match.

You, or anyone else kow of anything else I need to watch for?

Thanks guys,
