I've been using this live boot distro, Finnix to do some installation work on several virtual machines.
I'd like to modify the ISO file to include a script I need to do installations. I've booted the virtual machine and gotten as far as copying the
/dev/cdrom contents to a new Folder and modified it as needed.
Now I'd like to turn the plain folder back into a bootable ISO image and
nc it back to my host machine for subsequent boots, modified with my additional content.
How can I turn the folder with the modified content back into a bootable ISO image?
