        I'm also using an external package management system, but
whatever you're doing, you can usually do something like the following in
your kickstart file (assuming you install via kickstart):

----------------------------------
%post

# %post must be followed by a blank line

cd /root

URL1=<x>
URL2=<y>
URL3=<z>

/bin/rpm -Uvh $URL1/updates/*
/bin/rpm -Uvh $URL2/cfengine-2.1.0-0.fdr.1.p1.i386.rpm

wget $URL3/cfstartconf/update.conf
mv update.conf /var/cfengine/inputs/

wget $URL3/cfstartconf/ntp.conf
mv ntp.conf /etc/

chkconfig --add cfexecd
chkconfig --add ntpd

echo 'cfagent -q -vv -D setup | tee ~/cf.log' >> /etc/rc.local
----------------------------------

        This, as you'll probably recognise, installs the updates (best
done ASAP) and cfengine, copies across the cfengine config, and ensures
that cfagent is run immediately on startup.  It also ensures that the time
is synchronised -- without that, cfengine doesn't always work.  As far as
I know, it doesn't conflict with cfengine's package management stuff
either.

        :)
