response 1: *shrug*. that's their choice - and their problem.
response 2: you don't have to tell _me_ that - i'm the mad one who is
actively working on a debian/selinux distro!!! :)
response 3: _is_ it the job of debian developers to dictate the minimum
acceptable security level?
basically what i mean is, in gentoo, it's a no-brainer: you set options
at the beginning of your build, come back [2 weeks? :) ] later and you
have a system with PAX stack smashing, lovely kernel, everything
debian doesn't GIVE users that choice [remember the adamantix
bun-fight, anyone?] and instead settles for about the lowest possible
common denominator - no consideration to modern security AT ALL!

maybe it's just me with my weird setup [very likely], but
running mozilla under KDE 3.3.0 with selinux 184.108.40.206-selinux1
on a 256mb system P4 2.4Ghz) is a 10-11 second startup,
whereas if i set selinux=0 i've seen as fast as a THREE second
i've put KDE_IS_PRELINKED=1, KDE_FORK_SLAVES=1 into the
/usr/bin/startkde and i've run prelink, but i have the nvidia drivers
so the x-windows glx drivers are symlinks, which stops prelink from
being able to do its job on them.
also i recompiled kde 3.3.0 .debs with the latest gcc 3.3.
so i'm not _entirely_ confident that my setup is a good example to
