selinux and debian squeeze 9.5

[John Jasen <jjasen@gmail.com>]

For some reason, my attempts at enabling SELinux on a squeeze system
just aren't taking.

As I understand it, the following steps are required:

a) installing selinux-policy-default and dependencies

b) editing /etc/selinux/config to select default policy and permissive
or enforcing.

c) adding security=selinux to the grub boot line.

d) ensuring the filesystem selinux contexts are relabeled on reboot
(touch /.autorelabel)


However, for one particular test system, when it comes back up, SELinux
is disabled, and dmesg does not show SELinux in the kernel option line.
I feel like I'm missing something obvious, here.

Any suggestions?
