yes you have to manually clean up something

but since i upgraded > 20 servers since F9 to F14 and
currently stzart upgrade to F15 via yum this should also
work on CentOS and is mostly more painless than searching
every piece of configuraion on a new machine

since this is a new machine while the old is still there it
would be not a problem to test what is happening, on my
environments all servers are virtual-machines what makes
it all relaxter with a full snapshot
