How to update/mount/create ISO image as read write

Question

Is there a way to do the following in Linux:

1. Mount the ISO image as read/write
2. Create the ISO image as RW
3. Update the ISO image.

I am creating the image using the following command and the image "test.iso" mounts are read only preventing me to update the ISO files. "mkisofs -input-charset iso8859-1 -J -r -hide-rr-moved -joliet-long -o test.iso Test/"

Answer 1

1. No. The ISO9660 driver doesn't have any write support.
2. Meaningless. Either the filesystem driver has write support, or it does not. You can use a filesystem that does have write support such as ext2, but then you won't have a ISO image (although wodim and the like won't care, and will burn it regardless).
3. Use software such as ISO Master to do so.
