* Rewrite datactl command Prepare the target partition as part of the datactl command. Rely on partlabel for the target disk since we are always using GPT on the target disk. Use systemd and partlabel mechanism to wait and find the target data disk. Keep using the file system label to identify the source disk. Also use e2image instead of raw dd to move data. This should speed up the processes significantly. * Fix corner case when reusing same disk again
