I did double check it on F8 and NetworkManager is indeed chkconfig 98 2
meaning S98 and K02

I think your assessment is probably correct. I gathered from an earlier
explanation that the 'Live CD' uses NetworkManager by default and
thereby gather that an installation by a 'Live CD' would mimic that.

Obviously that would cause a few issues - such as the one under
discussion where ntpd starts before any network starts and I would think
that a bugzilla entry to NetworkManager should restart any services such
as ntpd upon establishing a network connection would be the end of
discussion.
