grml2iso - create a multiboot Grml ISO using grml2usb
grml2iso -o <target.iso> <ISO[s]>
Important! The Grml team does not take responsibility for loss of any data!
grml2iso allows you to create a multiboot Grml ISO. You can specify two or more Grml ISOs and will get one single multiboot ISO as a result. grml2iso requires and uses grml2usb for this task.
The order of the provided ISOs matters for two reasons:
1) order in boot menu entries: the first ISO specified is listed as first (default) option in the boot menu, further ISOs will be listed below as next options
2) EFI image to be used: the EFI image for booting via (U)EFI will be taken from the last provided ISO. Therefore to be able to boot on 64bit EFI systems, you need to provide a 64bit ISO (like grml64-small or grml64-full) as last ISO in the grml2iso command line.
grml2iso supports the environment variables GRML2USB and WRKDIR. GRML2USB specifies the path to the grml2usb script you’d like to use. WRKDIR specifies the work directory for creating the filesystem. The work directory needs at least as much free disk space as the sum of all specified ISOs.

# grml2iso -o /tmp/grml-multiboot.iso grml32-small_2020.06.iso grml64-small_2020.06.iso
Create multiboot ISO /tmp/grml-multiboot.iso with grml32-small_2020.06.iso and grml64-small_2020.06.iso.
# grml2iso -b 'lang=de ssh=passwd' -c /tmp/grml-content -o /srv/grml-multiboot.iso /srv/grml/grml32-small_2020.06.iso
Create a new ISO with additional boot parameters and copy the content from /tmp/grml-content to the generated ISO image.
# grml2iso -r quiet -r vga=791 -o /srv/grml-multiboot.iso /srv/grml64-small_2020.06.iso
Create a new ISO and remove existing boot parameters quiet and vga=791.
# GRML2USB=/srv/git/grml2usb/grml2usb grml2iso -o /srv/grml-multiboot.iso /srv/grml/grml32-small_2020.06.iso /srv/grml/grml64-medium_2020.06.iso
Create multiboot ISO /srv/grml-multiboot.iso with grml32-small_2020.06.iso and grml64-medium_2020.06.iso using /srv/git/grml2usb/grml2usb as grml2usb script.
# WRKDIR=/mnt/test/grml-tmp grml2iso -o /mnt/test/grml-multiboot.iso grml32-small_2020.06.iso grml64-small_2020.06.iso
Use /mnt/test/grml-tmp as working directory for creating the multiboot ISO /mnt/test/grml-multiboot.iso with grml32-small_2020.06.iso and grml64-small_2020.06.iso.
# grml2iso -p --skip-addons -o /srv/grml-multiboot.iso /srv/grml64-small_2020.06.iso /srv/grml64-small_2020.06.iso
Don’t copy the addons from the specified ISO images
