This is OT but FYI some virtualization apps have built-in support for exactly what you want, you can create disk images that share identical blocks between themselves. In Qemu/KVM this feature "copy-on-write disk images": $ qemu-img create -b base_image -f qcow2 new_image In Microsoft Virtual Server, there is also an equivalent feature but I can't recall how it is called. -marc _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
