       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 and installs grub2 as bootmanager on the multiboot ISO.


       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.

       -o <target.iso>
           This option is mandatory and specifies where the resulting multiboot Grml ISO should
           be placed. Note that (to avoid any possible data loss) grml2iso will exit if the
           specified target.iso exists already.

       -c <directory>
           The content of the specified directory will be copied to the resulting multiboot Grml

       -b <boot params>
           Use specified default bootoptions as default.

           Force the program to run and overwrite an existing ISO image.

       -r <boot param>
           Remove specified boot parameter from existing command line. Could be specified
           multiple times.

       -p <grml2usb param>
           Execute grml2usb with the specified parameters. For a list of valid parameters have a
           look at the grml2usb webpage[1] or the grml2usb manpage

       -s <URI>
           Generate a small ISO file which downloads the squashfs file from the specified URI.
           Due to current limitations in busyboxs wget and DNS resolution, an URL can not contain
           a hostname but an IP only. This is useful if you want to boot systems which support
           booting ISO image from your local system. Besides the iso image this command also
           copies the squashfs file to the output directory.


           # grml2iso -o /tmp/grml.iso grml_2009.05.iso grml64_2009.05.iso

       Create multiboot ISO /tmp/grml.iso with grml_2009.05.iso and grml64_2009.05.iso.

           # grml2iso -b 'lang=de ssh=passwd' -c /tmp/grml-content -o /srv/grml.iso /srv/grml/grml_2009.10.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.iso /srv/grml-small_2009.10.iso

       Create a new ISO and remove existing boot parameters quiet and vga=791.

           # GRML2USB=/srv/git/grml2usb grml2iso -o /srv/grml.iso /srv/grml/grml_2009.05.iso /srv/grml/grml64-medium_2009.05.iso

       Create multiboot ISO /srv/grml.iso with grml_2009.05.iso and grml64-medium_2009.05.iso
       using /srv/git/grml2usb as grml2usb script.

           # WRKDIR=/mnt/test/grml-tmp grml2iso -o /mnt/test/grml.iso grml_2009.05.iso grml64_2009.05.iso

       Use /mnt/test/grml-tmp as working directory for creating the multiboot ISO
       /mnt/test/grml.iso with grml_2009.05.iso and grml64_2009.05.iso.

           # grml2iso -p --skip-addons -o /srv/grml.iso /srv/grml-small_2009.10.iso /srv/grml64-small_2009.10.iso

       Don’t copy the addons from the specified ISO images
