title: How to get a backup of embedded Linux rootfs?
body: <p>I have an embedded Linux environment working well and want save the rootfs part, then to flash others new board with empty nand.</p>
  
  <p>So, what I tried. From barebox (before boot of the kernell), I put /dev/nand0.root.bb to the tftp server of my PC. </p>
  
  <p>Then I tried rename it in rootfs.ubifs and at the good place to call the "update -t rootfs" script from an other (and a new one) board.</p>
  
  <p>Size are different :
   17301504   original rootfs.ubifs
  264630784   /dev/nand0.root.bb</p>
  
  <p>Problem is system not booting correctly. </p>
  
  <p>Is there someone here who works in this way ? I need help... </p>
