I think my sentence lost some meaning when I wrote it down, it was more
of a whimsical observation and hope that rsbac (or something similar)
would one day be a mainline alternative.

OK. I've just read it. I found that to be strangly chilling reading. I
feel less assured after reading it. It was basically we have patents on
this, but we won't sue linux users. However, we can sell these patents,
and the new owner can do what they like, including sue linux users.

I think most of you are in the free world where software patents don't
apply. Unfortantly I no longer do, as my goverment signed a FTA with the
USA recently (what crack were they smoking when they did that ???) which
means I need to pay attention to crap like this.

After trying with SELinux I'll let you know if I run in to trouble with

Will test tonight/tommorow on a K6/2 and Athlon64 box.

That was a somewhat tongue in cheek observation that I feel it is
already server capable. I would have stuck with Debian otherwise.
