How can an ISO file be written (copied) to a disc as a single file using wodim?

Question

Problem

An ISO file needs to be 'burned' to a disc as a file, not an ISO image, and by using wodim.

Do you mean, creating a disc with a filesystem on it, in which the ISO image is a file? — Tom Hunt, Commented Nov 20, 2015 at 0:09
You mean you don't want to burn the iso image properly so that it is bootable, but just as a normal file? — psusi, Commented Nov 20, 2015 at 0:10
@psusi: Yes, that is correct. I do not want to burn the image, just copy the ISO file over as an ISO file. — Frugal Rasin, Commented Nov 20, 2015 at 0:25
Then you need to use genisoimage to create an iso image that only contains the iso file, and burn that with wodim... or just use a gui and drag and drop the file to the drive and burn it, which does just that. — psusi, Commented Nov 20, 2015 at 3:01
@psusi: The ISO has already been generated but as the question is asking, how can an ISO file be copied as a file to a cd/dvd using wodim? (And no GUI available here, only shell). — Frugal Rasin, Commented Nov 20, 2015 at 3:12

You can embed iso image into another iso image with mkisofs:

mkisofs -JR -o out.iso your.iso

Or just create a filesystem, for example ext2:

dd if=/dev/zero of=/path/to/image.ext2 bs=1M count=650
mke2fs -m0 /path/to/image.ext2

, mount it as a loop device and store your iso inside it:

mount -o loop /path/to/image.ext2 /mnt
cp /your/cd.iso /mnt
umount /mnt

Then burn resulting image.ext2 as usual with wodim.

If you need dvd size image, then change 650 to whatever dvd size will be acceptabe.

Yes, but that is not what the question is asking. What you have replied with is already obvious and using that command would create a CD/DVD of the ISO image file. The question is not to create a CD/DVD using the ISO image, but simply to write the file to the disc as a file, and to do so using wodim.

If you want to put in into other ISO image, then probably mkisofs is your tool of choice. Alternatively you can put it into any other filesystem image precreated, then write it to disc with same commands. Sorry for any misundrerstandings that were taken place.

Yes, that might be a way to do it. I will try it out then comment again so you can update/edit your answer. Here is what I will be doing: creating an ISO of the ISO, then burning the newly created 'outer' ISO using wodim.

It worked. So the answer is: Wrap the ISO in another ISO using an image creation tool (for example genisoimage), then write the new 'outer' ISO with wodim.

OK, so it's just my little misreading. Now it should be a proper answer!
