Currently I am playing with some disk images, and having to revert them rather more regularly than I would like. I was finding it a bit annoying waiting for cp commands to complete. As an alternative, there is rsync
Parted is all very well, but I found that needing to know the exact position of the partition was a bit of a pain.
Some old instructions for doing this are available at http://jonarcher.info/2015/02/getting-fedora-21-raspberry-pi-2/. I wanted to run these against an F22 image, getting ready for F23 coming out this month.
Now, Pixyll is lighter weight and more customizable than before.
