There are some warts with updates.  Use with care.  BTW, anyone
who has problems with the update process or with the installer (like
another thread where the installer pooped out on a specific RPM and
only allows you to retry and retry and retry), PLEASE squawk to RedHat
about it.  Anaconda is cool for the most part, but it needs a BIG
facelift.

No, only one is needed, but many folk only have ipchains experience
or filters, so it still exists.

Firewalls are iptables and/or ipchains.  If both are used, I think
iptables takes priority, but I'm not sure.

Not sure what you mean.  The quickie (default: medium) firewall setup
by RH 7.1/7.2 blocks all incoming connections except TCP and UDP DNS
(tcp/udp port 53).  I use Firestarter to tweak the settings.
