+Please do mind I create a 6G image to be used at a 8G CF disk as making it exactly fit, causes issues if sectors are wearing out. I create 2 x 2G partitions for the OS (and backup OS) and 1 x 1G partition for various configuration files and other shared stuff.
 
-Hack to __really__  have all old partition information is detroyed:
-build# dd if=/dev/zero of=$DA bs=1m count=1
+Hack to reload the usb card reader to reread partition tables:
