+
+# This is a *binary-hook* to allow disk installations from USB for
+# Debian 5.0.x Lenny. Place this file in config/binary_local-hooks/,
+# make it executable and rebuild your live image (binary only).
+
+# This workaround for debian-installer was adapted from Chris Lamb
+original patch:
+# http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=498143#5
+
+# It works by fooling apt-setup. With an existing /hd-media directory
+# apt-setup will not try to umount /cdrom. Enable live installer with
+# lh_config:
+#
+# lh_config --debian-installer "live"
+#
+# Rebuild your binary image. No options needed on boot.
