1. Install dependencies:

   Code Block
   # host sudo apt-get install multistrap qemu-user-static

2. Pick a working folder, in this case ~/duovero
 

3. Create a directory to hold the root filesystem:

   Code Block
   # host cd ~/duovero mkdir rootfs

4. Create a configuration file debian.conf in ~/duovero and paste in the following.  Additional packages can be included here or installed later using apt-get.  

   Code Block

   [General] arch=armel directory=~/duovero/rootfs retainsources=~/duovero/sources cleanup=true noauth=true unpack=true bootstrap=Wheezy Net Utils aptsources=Wheezy [Wheezy] packages=apt locales udev adduser sudo nano build-essential less source=http://mv.ezproxy.com.ezproxyberklee.flo.org/debian suite=wheezy [Net] packages=netbase ifupdown iproute net-tools iputils-ping ntp source=http://mv.ezproxy.com.ezproxyberklee.flo.org/debian [Utils] packages=wget source=http://mv.ezproxy.com.ezproxyberklee.flo.org/debian

5. Run multistrap to create the root filesystem.  

   Code Block
   # host multistrap -a armel -d ~/duovero/rootfs -f debian.conf

6. Copy the QEMU ARM emulator into the new root filesystem so it is on the path when we chroot in.  

   Code Block
   # host sudo cp /usr/bin/qemu-arm-static ~/duovero/rootfs/usb/bin/

7. (Optional) If you need /dev/random (for installing openssh-server for example), mount /dev in the chroot.  

   Code Block
   # host sudo mount -o bind /dev ~/gumstix/rootfs/dev

8. Chroot into the new filesystem.  

   Code Block
   # host sudo chroot ~/duovero/rootfs /bin/bash

9. Finish setting up packages 

   Code Block
   # chroot dpkg --configure -a

   Answer "no" when prompted to use "dash" as "/bin/sh".  If any packages fail to configure (possibly ifupdown), just run dpkg again.  

10. Set the root user password.

    Code Block
    # chroot passwd

11. (Optional) Add a new user and give it sudo permissions 

    Code Block
    # chroot adduser mit printf "mit ALL=(ALL) ALL" >> /etc/sudoers

12. Configure locales.  Choose 136 for en_US.UTF-8.  

    Code Block
    # chroot dpkg-reconfigure locales

13. Add a DNS server 

    Code Block
    # chroot printf "nameserver 8.8.8.8" > /etc/resolv.conf
