I originally packaged the GR Security kernel patch for Debian and I'm working
on SE-Linux (which is one of the security modules for LSM). I have not been
having religious arguements with myself. ;)

If you want a nice easy way of locking down chroot's then GRSec is what you
If you want a kernel patch that has a heap of different security improvements
that are easy to use then GRSec is what you want.
If you want something that you can deploy on your server right now then LSM
is not an option.
LSM is a modular security architecture that currently supports SE-Linux and
(in 2.5.5) LIDS. It does not have some of the features of GRSec (network
security improvements, chroot lock-down, easy lock-down of "ps aux" and
"dmesg"), but apart from the network security patches it can all be done in
SE Linux configuration.
SE Linux is much harder to configure than GRSec. At the moment there is a
lack of documentation and a lack of sample files for the common cases.
Expect to spend at least a week of full-time work if you want to get SE Linux
configured for your system!
Also my packages of SE Linux programs are experimental and some of them break
