#!/usr/bin/env bash
# build your own Raspberry Pi SD card
#
# by Klaus M Pfeiffer, http://blog.kmp.or.at/ , 2012-06-24
# 2012-06-24
# just checking for how partitions are called on the system (thanks to Ricky Birtles and Luke Wilkinson)
# using http.debian.net as debian mirror, see http://rgeissert.blogspot.co.at/2012/06/introducing-httpdebiannet-debians.html
# tested successfully in debian squeeze and wheezy VirtualBox
# added hint for lvm2
# added debconf-set-selections for kezboard
# corrected bug in writing to etc/modules
# 2012-06-16
# improoved handling of local debian mirror
# added hint for dosfstools (thanks to Mike)
# added vchiq & snd_bcm2835 to /etc/modules (thanks to Tony Jones)
# take the value fdisk suggests for the boot partition to start (thanks to Mike)
# 2012-06-02
# improoved to directly generate an image file with the help of kpartx
# added deb_local_mirror for generating images with correct sources.list
# 2012-05-27
# workaround for https://github.com/Hexxeh/rpi-update/issues/4 just touching /boot/start.elf before running rpi-update
# 2012-05-20
# back to wheezy, http://bugs.debian.org/672851 solved, http://packages.qa.debian.org/i/ifupdown/news/20120519T163909Z.html
# 2012-05-19
# stage3: remove eth* from /lib/udev/rules.d/75-persistent-net-generator.rules
# initial
# you need at least
# apt-get install binfmt-support qemu qemu-user-static debootstrap kpartx lvm2 dosfstools
