     breaks the way grml-debootstrap used to work. Instead:
   * Introduce option --nopackages to skip installation of packages
     defined in /etc/debootstrap/packages.
+  * Support config variable RM_APTCACHE to allow disabling removal
+    of apt-cache. Thanks for the idea and initial patch, Tong Sun.
