OpenBSD: Mount An ISO Image Command

by on May 16, 2013 · 2 comments· LAST UPDATED May 16, 2013


How do I mount an ISO image in OpenBSD operating systems using command line options?

You can mount a disk image or ISO images using the mount command. This is useful if you want to copy a few files from an ISO image without burning the image to CD or DVD. You need to use the following commands:

DifficultyIntermediate (rss)
Root privilegesYes
Estimated completion timeN/A
a] vnconfig - The vnconfig command configures vnode pseudo disk devices.

b] mount - Mount file system.

c] umount - Unmount file systems


The syntax is:

vnconfig /dev/vndXy /path/to/file.iso
vnconfig vnd0 /tmp/file.iso
mount /dev/vndXy /mnt/


In this example, mount an ISO disk image called /home/nixcraft/downloads/foo.iso:
# vnconfig vnd0 /home/nixcraft/downloads/foo.iso
# mount -t cd9660 /dev/vnd0c /mnt
# df
# cd /mnt
# ls -l
# cp xyz /home/nixcraft/

To unmount the image, enter:
# umount /mnt
### Detaching vnode device from the image ###
# vnconfig -u vnd0
