       grml-rescueboot  integrates  Grml ISO booting into GRUB. It provides a script for update-grub which looks
       for Grml ISO images in /boot/grml, and automatically adds an entry for each image. The purpose is to  use
       one of those images to boot a Grml rescue system without using a CD, USB stick or network boot (PXE).

       update-grml-rescueboot   is   a  script  which  checks  for  the  latest  stable  version  of  Grml  (via
       download.grml.org), ensures there is enough free disk space  in  /boot/grml  and  downloads  the  ISO  to
       /boot/grml.  It  verifies the ISO signature and upon success executes update-grub then. Everything should
       be ready for booting a Grml ISO via GRUB then.

       This script makes it even easier to integrate a Grml ISO into GRUB via grml-rescueboot. All that needs to
       be done is to install grml-rescueboot and then invoke update-grml-rescueboot. Using the -t option, it  is
       possible  to  use  specific  Grml  ISOs. If this option is not specified, it defaults to the full flavour
       matching the hardware architecture (amd64 or arm64).

-f     Force execution, ignoring, e.g. existing ISO files and disk space checks for /boot/grml.

       -h     Display usage information and exit script.

       -targ Choose Grml flavour, specified via arg. Supported  flavours  are  'small'  and  'full'.  If  unset
              defaults to 'full'.
