• did you dd an image of whole disk with multiple partitions and need to loop mount only one? use losetup -P
  • losetup -f # use first available, e.g.
  • losetup -P /dev/loop0 /path/to/disk.img
  • ls /dev/loop*
  • mount /dev/loop0p2 /mnt # if 2nd partition was needed
  • you can even fdisk /dev/loop0
• or harder? offset mount with block-size * block-#
• sync & backup, see Arch Wiki
• copy compressed images with netcat
• for virtual guests see virsh
