hdik(8) BSD System Manager's Manual hdik(8)
NAME
hdik -- lightweight tool to attach and mount disk images in-kernel
SYNOPSIS
hdik imagefile [options]
DESCRIPTION
hdik is a lightweight tool that can be used to attach disk images in-kernel (i.e. without a user-land process to provide the backing store).
Only a subset of disk images can be mounted in this manner including read/write disk images, UDIF disk images that use zlib compression,
shadowed disk images, and sparse disk images.
hdik is intended for use in situations where linking against the DiskImages framework is problematic or an extremely lightweight mechanism
for attaching a disk image is needed.
You can specify that the image should not be processed by Disk Arbitration by specifying the -nomount option. You can also specify that the
image be mounted with a shadow file by using the -shadow option.
The following argument must be specified:
imagefile the disk image to be mounted.
OPTIONS
-shadow [shadowfile]
Use a shadow file in conjunction with the data in the image. This option prevents modification of the original image and allows
read-only images to be used as read/write images. When blocks are being read from the image, blocks present in the shadow file
override blocks in the base image. When blocks are being written, the writes will be redirected to the shadow file. If not
specified, -shadow defaults to <imagename>.shadow. If the shadow file does not exist, it is created.
-nomount Suppress automatic mounting of the image or partitions on it. This will result in /dev entries being created, but will not mount
any volumes.
-drivekey keyname=value
Specify a key/value pair for the IOHDIXHDDrive object created (shows up in the IOKit registry of devices which is viewable with
ioreg(8)).
