== Restricting Xephyr connections ==
 +
Most X11 servers are configured to disable TCP connections. This means that in order to get a working X connection we can:
 +
 +
# bind-mount the X unix socket into the chroot.
 +
# ssh ''into'' the chroot with X11-forwarding enabled.
 +
# Enable TCP on an X server, e.g. a nested Xephyr.
 +
 +
In the main walk-through, we chose to use an open Xephyr like so:
 +
 +
Xephyr -ac :1
 +
 +
However, we might instead try:
 +
 
  # ''outside chroot''
 
  # ''outside chroot''
 
  DISP=:1  # adjust to suit your configuration
 
  DISP=:1  # adjust to suit your configuration

  chmod a+x as_person
 
  ./as_person sugar /usr/bin/sugar
 
  ./as_person sugar /usr/bin/sugar

== Using xz utils ==
 +
 +
this step must be reformed,
 +
 +
curl http://dev.laptop.org/~mstone/releases/SOURCES/$NV.tar.xz | tar Zxf $NV.tar.xz
 +
 +
because tar doesn't suggest it (for now)
 +

this is at least in debian/ubuntu
