Yes, this is true.
Sergei, this should do the job for you and your friend. I have only
used this up to FreeBSD 4.10. Therefore, if vnode support is
different in 5.x, it may need some updating.
To install, just put the script anywhere in your path. umount_iso
should be a link (soft or hard) to mount_iso. It looks at how it was
called to decide what to do. I also suggest that you sudo it, so you
do not need to be root to run it.
BTW, this comes with the usual disclaimer. Should it thrash your file
system, cause your computer to explode, whatever, I am not liable.
However, if anybody hits any bugs in this, I would greatly appreciate
hearing about them.

# File: mount_iso
# Description: Mounts an iso image file onto a mount point for previewing.
# Usage: mount_iso iso_file mount_point
# or umount_iso mount_point
###################################################################
# Works with FreeBSD, Linux and Solaris. Should work with other BSDs
# too, as long as they have vnode support.
#
# For FreeBSD, the kernel needs to have vnode support compiled in.
# See "man vn".
#
# For Solaris pre version 8, lofiadm does not exist.
# You need to install the fbk driver and modify the script to use it.
####################################################################
# Installation: Put this script somewhere in your path and make a hard link
# to it called umount_iso.
