To use the enhanced loopback driver, here's a basic example: Install the new boot configuration and reboot! (select the new kernel) The createdev script makes the new loop device names (/dev/loopa, /dev/loopb). Make sure if you are booting off of a SCSI drive that you re-create and use an initrd file (unless you know the SCSI driver is built into the kernel). The name of this kernel is /boot/vmlinuz-2.4.xx-xfs-enhanced_loop. Then go and edit your nf or nf (or whatever boot utility you use) and add in another option to boot the new kernel. Tar xvfz /path/to/vmlinuz-2.4.xx-xfs-enhanced_loop.x.tar.gz Most important to us is providing automatic interpretation and mapping of partitions contained within an image file of a hard drive.įor most people, here's what you need to do:ġ) Download binary/vmlinuz-2.4.xx-xfs-enhanced_loop.x.tar.gzĢ) Download binary/loop-utils-0.0. The enhanced loopback driver modifies the native loopback driver of the Linux kernel and adds functionality that can make the driver emulate a disk drive in some ways. The following documentation is an amalgam of Jason Luttgens's USE.txt, readme.txt, and INSTALL.txt: Older and more complex to setup than above options. 1.4 Linux Enhanced Loopback DriverĪvailable from Sourceforge or NASA's FTP server. Libguestfs also includes guestmount, which can mount disk images directly into the local filesystem. įor exFAT support at the moment (Oct 2016), create zz-exfat like so: # echo exfat-fuse > /usr/lib/x86_64-linux-gnu/guestfs/supermin.d/zz-exfat # echo exfat-utils > /usr/lib/x86_64-linux-gnu/guestfs/supermin.d/zz-exfat It can access proprietary systems like VMware and Hyper-V." # apt install libguestfs-tools # guestfish -ro -a disk.img > run. It can access disk images on remote machines or on CDs/USB sticks. It can do it securely - without needing root and with multiple layers of defence against rogue disk images. # kpartx -a -v os9.img add map loop0p1 (252:0): 0 63 linear /dev/loop0 1Īdd map loop0p2 (252:1): 0 54 linear /dev/loop0 64Īdd map loop0p3 (252:2): 0 74 linear /dev/loop0 118Īdd map loop0p4 (252:3): 0 54 linear /dev/loop0 192Īdd map loop0p5 (252:4): 0 74 linear /dev/loop0 246Īdd map loop0p6 (252:5): 0 200 linear /dev/loop0 320Īdd map loop0p7 (252:6): 0 512 linear /dev/loop0 520Īdd map loop0p8 (252:7): 0 512 linear /dev/loop0 1032Īdd map loop0p9 (252:8): 0 3330884 linear /dev/loop0 1544Īdd map loop0p10 (252:9): 0 10 linear /dev/loop0 3332428 # mount /dev/mapper/loop0p9 /mnt -o ro # ls /mnt Applications (Mac OS 9) Documents Trashĭesktop Folder TheVolumeSettingsFolder # umount /mnt # kpartx -d os9.img loop deleted : /dev/loop0 1.3 guestfish (part of libguestfs) "libguestfs can access almost any disk image imaginable.
