Well what I want to do is to create a layer around the normal
filesystem, using a FUSE fs. Maybe you've read earlier about this,
I've send a proposal about this to the meeting in Berlin
Guadec/Akademy.

The FUSE fs and several make the system for the user look like:

/Computer
/Home
/Internet Services
/Home
/Network
/Mounts
/Shared
/System


To make this work several scripts are run at the begin of a session
(and to clean when session stops)

Roughly it comes to:

1. determine settings
2. if settings say so:
2a. setup environment in /var/lib/workspace/%USER/chroot by mounting
FUSE fs fuse-workspace and remounting the normal system to it.
2b do a chroot using pam_chroot

Now I see that the chroot is deprecated, namespaces are better. I'm
not familiar with it, and reading about it now.

But what I want is to run some scripts when a session starts (and when
it ends) to run a "determine settings" and create a "namespace".

I've looked to pam_namespace, but I need more.
