What a lovely idea! :)

Yes, it's possible to get what you want - without having to use
grml-live. :)

I just implemented support for loopback devices in grml2usb.
Please grab the current version of the script and give it a try:


Note: to build a bootable ISO you've to generate the according
eltorito boot image. As grml2usb can generate the configuration
files for syslinux/grub already I just wrote a script which
generates the eltorito boot stuff. All the steps from 0 to a
multiboot ISO are implemented in the following script:


Just adjust it according to your needs. It's a bit hackish for now,
though it should do what it's supposed to do. I'm thinking about
providing an official grml2usb-to-iso script as part of the official
grml2usb suite.

Please let me know if it works for you, then I'd upload a new
grml2usb version and work on a final solution of grml2usb-to-iso.

No problem, it's just fine - I'm not a native english speaker as
well. ;)

Sure, no problem - just works with the steps mentioned above. :)
