NAME¶

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

SYNOPSIS¶

update-grml-rescueboot [-f] [-a 32|64|96] [-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's 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 integration of a Grml ISO into GRUB via grml-rescueboot even easier. All that needs to be done is install grml-rescueboot and invoke update-grml-rescueboot afterwards. Using the -a and -t options it's possible to use specific Grml ISOs. If none of those options is specific it defaults to the grml-full flavour, matching the currently running hardware architecture (i?86 or x86_64).

OPTIONS¶

-a arg

Choose Grml architecture, specified via arg. Supported flavours are '32', '64' and '96'. If unset defaults to the currently running architecture.

-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'.
