Here is the crib sheet I wrote when I set this up, it was on a Debian
Wheezy system, but my ARM chroot contains Ubuntu Precise as that is what
I am targeting in my day job. (Hopefully Debian will work too.)
# in these instructions "/arm" is the directory where I installed my
# chroot and "tixy" is my linux username, replace as appropriate...
#
# /data is where I have all my source code and other files so I add that
# to schroot fstab below, do similar with directories where you have
# files you want to access inside the chroot. (Note, home directories
# are already available.)
