I disagree with these. What home user would do this and then still have
time to browse properly and use the computer?

Real-life steps:
1. install only needed software. Don't perform an "everything" install
if you don't need everything.
2. enable firewall in anaconda at install time. Don't enable any ports
if you don't need them
3. System Settings -> Server Settings -> Services. Enable iptables, look
at others if they are needed.
4. Install tripwire from fedora extras
5. skim through root's mails (tripwire, logwatch)

Suggestions welcome.
