I've installed SELinux in Debian sid in order to use the sandbox that locks down apps to a restricted enviroment, but I can't get it to work. If I try to use the sandbox command in permissive mode without any options, like sandbox nano, I get the following error:

/usr/bin/sandbox: [Errno 22] Invalid argument

And if I try to run it with options for temporary home and tmp dirs, with or without the -X option, another error message pops up:

Could not set exec context to unconfined_u:unconfined_r:sandbox_x_t:s0:c236,c539.
Failed to remove directory /tmp/.sandbox-root-vfZJIt: No such file or directory

I have tried using the sandbox app in enforced mode, but it complains about missing type enforcement rules. I don't think that's the issue though. Does anyone know how to fix this?

It seems that the sandbox policy module isn't loaded. If I run semodule -l the sandbox module doesn't show up. Does anyone know how to load the sandbox policy module in Debian? –  Magnus May 2 '12 at 3:31
