To mount an iso image under FreeBSD just follow these steps.
Create a loop-back device with
# mdconfig -a -t vnode -f PATH_TO_YOUR_ISO/ISOFILE.iso
Mount the create vnode to a folder (Replace
/dev/mdX with your device
# mount -t cd9660 /dev/mdX /cdrom
The md device is automatically created by
mdconfig and the name is
printed after the command has been executed e.g.
After you have unmounted the directory you can destroy the md-device with
the following command:
# mdconfig -d -u X
X is the device number e.g.
1 and so forth.
