# update-grml-rescueboot(8)

Script to integrate Grml ISO for booting via GRUB

## NAME

update-grml-rescueboot - Script to integrate Grml ISO for booting via GRUB

## SYNOPSIS

**update-grml-rescueboot \[-f\] \[-t** *small\|full***\]**

## DESCRIPTION

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).

## OPTIONS

- **-f**

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

- **-h**

  Display usage information and exit script.

- **-t** *arg*

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