extract iso image

[T.F. Cheng]

hi, I am not sure if I am doing the right thing. I
want to extract an downloaded isoimage by first
mounting it. I tried: mount -t iso9660 -o loop
image.iso /mnt but turns out I don't have
mount_iso9660 under /sbin, only mount_cd9660. Is there
any other way to do this? I am running
freebsd5.3/i386. Thanks!

Look in the handbook under optical drives.

I could be doing things the hard way, but I thought you had to
first configure the md? For instance, I pulled the following
commands from history (just recently upgraded my firewall):

mdconfig -a -t vnode -f /dat1/ISO/obsd_36.iso -u 0
mount_cd9660 /dev/md0 /mnt

HTH,

Is my best guess you have been reading Linux docs to have tried a
"loop" option to mount in FreeBSD. Isn't done that way here.

What you have to do is create a memory disk which is backed by a file.
Maybe someone else knows how to do it as non-root:

% su
Password:
# mdconfig -a -t vnode -o readonly -f dvd_image.iso
md0
# mount -t cd9660 /dev/md0 /mnt
# ls -CF /mnt
audio_ts/ jacket_p/ video_ts/
# umount /mnt
# mdconfig -d -u md0
# mdconfig -l

#

What happens is that mdconfig creates the md0 device which contains the
contents of the specified file. Once the file is turned into a device
it can be handled same as any other device.

Be sure to deallocate the device after you are finished as Unix doesn't
release a file's space allocation until the last process closes it.

Linux calls it iso9660, FreeBSD calls is cd9660, same thing.
The freebsd command that does the same thing is as follows:

mount -t cd9660 /dev/`mdconfig -a -t image.iso` /mnt
