Decided to mount it on my SuSe VM and do it via that.  Next will be to boot and see if the SD still works if it does img it clone to the new PI's.  Once the partition has been reduced do a dd dump #dd if=/dev/sdb of=/mnt/backup/image256.img on the dd'ed image check the size # fdisk -l image256.img Disk image256.img: 16.0 GB, 16012804096 bytes, 31275008 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk label type: dos Disk identifier: 0x00090806 Device Boot Start End Blocks Id System image256.img1 8192 122879 57344 c W95 FAT32 (LBA) image256.img2 122880 5151223 2514172 83 Linux Now truncate to the end +1 # truncate --size=$[(5151223+1)*512] image256.img use whatever to write it to your SD card  | The basic idea is to use the Raspberry PI as a monitor for some thing fishy. I originally hacked something together for a B board but thought I would document the creation for the B+ as I am in need of a stable platform for use vs development. 1) Basic configuration Grab the latest image of RASPBIAN - as at 30 September 2014 Use Win32DiskImager or whatever the instruction are on the site to write this to the MicorSD Card. (Using a Lexar 16G 300x ) Do your normal setup on boot (sudo raspi-config if you missed something)
advanced options
and reboot Your system should come back with an IP of DHCP and you can log on via your usb keyboard user pi and the password the one you set above. Have a look at what your IP is and that you have no errors (warning are OK) Remote keyboard and HDMI display and use a ssh client to access your RPI. I like to use mobaxterm from http://mobaxterm.mobatek.net/ BTW current config - 5.13 Volt @ 210-230mA (got one of those in-line USB charger doctors) 3) Getting Webmin installed. more or less from: http://c-mobberley.com/wordpress/2013/12/24/raspberry-pi-webmin-install-updates-via-apt-get/ pi@pibplus ~ $ sudo nano /etc/apt/sources.list add deb http://download.webmin.com/download/repository sarge contrib deb http://webmin.mirror.somersettechsolutions.co.uk/repository sarge contrib Get the key pi@pibplus ~ $ cd ~ pi@pibplus ~ $ wget http://www.webmin.com/jcameron-key.asc add the key pi@pibplus ~ $ sudo apt-key add jcameron-key.asc pi@pibplus ~ $ sudo apt-get update pi@pibplus ~ $ sudo apt-get install webmin in a web browser you should now be able to access webmin on port 10000   6) getting some shots with the camera pi@pibplus ~ $ sudo raspi-config  have some fun pi@pibplus ~ $ sudo apt-get install lighttpd pi@pibplus ~ $ sudo chown www-data:www-data /var/www pi@pibplus ~ $ sudo chmod 775 /var/www pi@pibplus ~ $ sudo usermod -a -G www-data pi test pi@pibplus ~ $ sudo raspistill -o /var/www/cam2.jpg  Editing images some details from here: http://superuser.com/questions/649033/ubuntu-add-timestamp-to-image pi@pibplus /var/www $ sudo apt-get install imagemagick pi@pibplus /var/www $ sudo apt-get install exiv2  8) things to consider http://pitography.github.io/BerryCamExpress/ wget http://node-arm.herokuapp.com/node_latest_armhf.debsudo dpkg -i node_latest_armhf.debgitclone https://github.com/pitography/BerryCamExpress.gitcd BerryCamExpressnpm installcd dist node berrycam-server.js /opt/vc/bin/raspistill --exif IFD1.Software=BerryCam -x EXIF.MakerNote=BerryCam -x EXIF.UserComment=BerryCam --awb Fluorescent --ev -6 --ISO 400 --output berrycamimages/session_2014-10-04/0073.jpg --width 1944 --height 1458 --quality 100 --metering Matrix --exposure Night --sharpness 12 --brightness 48 --contrast -16 --saturation -25 --imxfx None --vflip --timeout 1000  9) Updating firmware at some point I landed on a firmware version that put my pi's into a boot loop while the usb wifi was plugged-in. Went down to a know working version by  root@c15:/boot# sudo rpi-update de69b134dc6e4066fe70db29816d57895dffd9b9 the above downgrade me from 3.12.30+ to depmod 3.12.28+ you can find the latest version here https://github.com/Hexxeh/rpi-firmware/commits/master.
