> prepare_all_disks.sh works, but not well in some cases. EC2 reports /dev/sdX as the disks to jclouds, but the actual devices on the VMs is often /dev/xvdX, without symlinks etc. So we should check for that in the script and switch over to /dev/xvdX if needed.
> Also we should get rid of the obsolete/unused prepare_disks.sh.
