* Do chroot builds in a private namespace. This means that all the

Browse source 
bind-mounts we do are only visible to the builder process and its
  children.  So accidentally doing "rm -rf" on the chroot directory
  won't wipe out /nix/store and other bind-mounted directories
  anymore.  Also, the bind-mounts in the private namespace disappear
  automatically when the builder exits.
