SELinux works like a charm in Ubuntu!

[Joel Bryan Juliano]

SELinux does wonders on my Feisty machine. I noticed that when it's turn on,
applications don't get any noticeable delays when loading, I can run QEMU
now without sacrificing the performance of the host OS. Everything runs so
smooth. Networking also runs well without any problems, Sharing files using
gshare (Avahi FTP Daemon), SAMBA works, and other host can connect to me
without problems. I can even connect to this PC by my .local address and
grab the correct time in the internet using ntpd. I have done alot of
searching on the net because I was so reluctant about it, I have fears about
the effects on compiling a program, but couldn't find any, so I just tried
it myself and to my surprise It works like a charm, and doesn't affect the
compiled programs.

The only settings that is not working in Ubuntu is enforcing mode, which
will not boot the machine, but permissive with strict policy works. I'm
using targeted policy.

To install SELinux, just grab selinux-basics and it would install the
targeted policy. The strict policy and src policy would have to be installed
manually. After that you'll have to enable it at boot with selinux=1 option.

Just sharing this wonderful features most of us doesn't use.
