Very bare bones script to make a raspberry pi chroot for development. Anyone else WILL need to modify it.
Assumed Vars: IMAGE_FILE="2014-01-07-wheezy-raspbian.working.img" CHROOT_DIR="/mnt/rPI" WORK_DIR="/home/bavery/src/rPi-workspace" LOOP="/dev/mapper/loop0p2"
dependencies sudo apt-get install kpartx wget http://downloads.raspberrypi.org/raspbian_latest -O raspian-latest.zip unzip raspian-latest.zip cp 2014-01-07-wheezy-raspbian.img 2014-01-07-wheezy-raspbian.working.img
Note: the 2014-01-07-wheezy-raspbian.working.img file will change each time you enter, do stuff and exit. The stuff in the working directory won't affect it but anything installed will.
