How to mount and read cdimage before burning

[Stephen Liu]

Hi folks,

Freebsd 5.2
===========

Following command works on Linux but not on Freebsd
# mount cd_image.iso -r -t iso9660 -o loop /mnt
(remark: iso9660 changed to cd9660)

Google search brought following link
http://www.freebsddiary.org/iso-mount.php

$ vnconfig /dev/vn0c cd_image.iso
ERROR: vnconfig(8) has been discontinued
        Please use mdconfig(8).
$ mdconfig /dev/vn0c cd_image.iso
mdconfig: open(/dev/mdctl): Permission denied
$ su
Password:
# mdconfig /dev/md0c cd_image.iso
usage:
        mdconfig -a -t type [-n] [-o [no]option]... [
-f file] [-s size] [-S sectorsize] [-u unit]
        mdconfig -d -u unit
        mdconfig -l [-n] [-u unit]
                type = {malloc, preload, vnode, swap}
                option = {cluster, compress, reserve}
                size = %d (512 byte blocks), %dk (kB),
%dm (MB) or %dg (GB)

Have no idea how to proceed further.  Kindly advise.

TIA

B.R.
