update-grml-rescueboot \- Script to integrate Grml ISO for booting via GRUB
.SH SYNOPSIS
\fBupdate-grml-rescueboot [-f] [-a \fI32|64|96\fB] [-t \fIsmall|full\fB]
\f1
.SH DESCRIPTION
grml-rescueboot integrates Grml ISO booting into GRUB. It provides a script for update-grub which looks for Grml ISO images in \fI/boot/grml\f1, 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). \fIupdate-grml-rescueboot\f1 is a script which checks for the latest stable version of Grml (via download.grml.org), ensures there's enough free disk space in \fI/boot/grml\f1 and downloads the ISO to \fI/boot/grml\f1. 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 \fI-a\f1 and \fI-t\f1 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).
