   [jessie] description Debian Jessie (stable) type=directory directory=/srv/chroot/jessie users=clint root-users=clint root-groups=root aliases=stable,default

4. create Debian Jessie chroot

    $ sudo apt install debootstrap
    $ sudo debootstrap jessie /srv/chroot/jessie http://httpredir.debian.org/debian
   

5. schroot into and configure chroot

    $ schroot -c jessie -u root
    # apt update && apt install curl
    # dpkg --add-architecture armhf
    # tee "deb http://emdebian.org/tools/debian jessie main" /etc/apt/sources.list.d/crosstools.list"
    # curl http://emdebian.org/tools/debian/emdebian-toolchain-archive.key | apt-key add -
    # apt update
    # apt install crossbuild-essential-armhf cmake
    # logoff
   

6. test schroot toolchain

    $ schroot -c jessie
    $ arm-linux-gnueabihf-gcc --version  # should be 4.9
   

7. create user-editable project folder

    $ schroot -c jessie -u root
    # mkdir /project
    # chown clint:clint /project
    # logoff
    $ git clone https://github.com/clintliddick/b4 /srv/chroot/jessie/projects/b4
