- What this does: 
-   
- This generate a build of ubuntu for raspberry 2 [B][+] with swap, self-configured user, 
- password, software (from repo) and configs (e.g. ssh-server for headless using) 
-   
- You MUST edit  rpi2-settings.sh ! 
- You SHOLD edit rpi2-extra_files.sh ! 
-   
- The default-config install a ubuntu 14.04 server with ssh-server, mc, vim, w3m, german-language... 
-   
- Needed Software: 
-   
- must-have: qemu-debootstrap (paket: qemu-user-static) 
- must-have: debootstrap 
- nice to have: bmap-tools (for faster writing) 
- (sudo apt-get install debootstrap qemu-debootstrap bmap-tools will executed by rpi2-build-system.sh) 
-   
-   
- It is a good idea to use a own [apt-]proxy. (e.g.: apt-cacher-ng) 
-   
- Simple usage: 
-   
- 1.) Edit rpi2-settings.sh and extra_files.sh. SetT WriteTo='mmcblk0' 
- 2.) Put the mmc-card into the slot (If you want to create on. Note: you will LOST ALL data on the card!) 
- 3.) Run sudo ./rpi2-clear.sh 
- 4.) Run sudo ./rpi2-build-system.sh 
-   
- Extended usage: 
-   
- 1.) Edit rpi2-settings.sh and extra_files.sh. SET WriteTo='none' 
- 2.) Run sudo ./rpi2-clear.sh 
- 3.) Run sudo ./rpi2-build-system.sh 
- 4.) Make your changes into the build-directory 
- 5.) Write the mmc-card with sudo ./rpi2-create-mmcblk0.sh
