loopmount Command

Purpose

Associate an image file to a loopback device. Optionally, make an image file available as a file system via the loopback device.

Syntax

loopmount { -i imagefile | -l device } [-o mount options -m mountpoint ]

Description

This command is similar to mount except that it creates a loopback device if not specified, binds the specified file to it, and optionally mounts it. If the command implicitly creates a new loopback device, it sets the temporary attribute in CuAt to yes so that it will be deleted by subsequent loopumount or reboot. All the restrictions and features of the mount command apply to loopmount also.

Flags

If -l and -i are both specified, the imagefile is associated with the device before mounting it.

Examples

1. The following mount an ISO image on /mnt.

   $ loopmount -i cdrom.iso -o "-V cdrfs -o ro" -m /mnt

2. The following mounts a disk image on /mydisk with loop2. The image file was bound to loop2 earlier with chdev command.

   $ loopmount -l loop2 -o "-V jfs2 -o rw,log=NULL" -m /mydisk

   In case the filesystem was created with an INLINE log, this INLINE log can be used.

   $ loopmount -l loop2 -o "-V jfs2 -o rw,log=INLINE" -m /mydisk

3. The following mounts an image file bound to loop0 on /mnt.

   $ loopmount -i mycd.iso -l loop0 -o "-V cdrfs -o ro" -m /mnt
