Hi, I'd like to create a bootable DVD from the ISOs of grml and grml64 so I can boot whichever of the two flavors or even aggregate the rest of the ISOs to the DVD (small and medium for i585 and amd64).
What a lovely idea! :)
I tried to use grml2usb doing this:
- dd if=/dev/zero of=dvd.iso bs=1M count=2000
- losetup /dev/loop1 dvd.iso
- echo -en "n\np\n1\n\n\nt\n6\na\n1\n w\n" | fdisk /dev/loop1
- mkfs.vfat /dev/loop1
- grml2usb grml_2009.05.iso grml64_2009.05.iso /dev/loop1
But it didn't work. There's seems to be some problem when installing the bootloader.
What did you think?, Is it possible to do what I want?, should I use grml-live to create custom ISOs?.
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:
http://git.grml.org/?p=grml2usb.git;a=blob_plain;f=grml2usb;hb=HEAD
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:
http://grml.org/tmp/grml2usb-to-iso.sh
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.
Greettings and excuse for my english but it's now my native language.
No problem, it's just fine - I'm not a native english speaker as well. ;)
PS: if it can be done, I'd like to make a CD with for example grml-medium and grml64-medium on it too
Sure, no problem - just works with the steps mentioned above. :)
