update-grml-rescueboot8

Usage

Overview

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'.
