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