What exactly do I gain by doing it? What have I protected myself from?

If you understand what SELinux is, the gain is immediately obvious. Here
is a recent article

Hi Rahul

Thanks for the link to that article above. For the first time when installing
a distro, I'd left Selinux enabled (enforcing) for Fedora 7. There had been
no problems, but today I tried to FTP into it from the other machine with no
success. I ran tail -f /var/log/messages on fedora 7, and tried to FTP in
again from the other machine, and immediately saw it was an Selinux problem.

The article showed setroubleshoot, so I thought I may as well try and fix the
problem, so I fired it up, and it showed how to fix the FTP problem with a
simple: (if I've remembered the command correctly)
setbool -P ftp_user_dir=1

It worked like magic. I hope any other Selinux problems that crop up on Fedora
7 are as easy to fix.

All the best.

Nigel.
