# 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.
