Oops, it occurs to me that if you are booting from a CD, you can't do an 
eject. I always run grml from a thumb drive. That is why I forgot about 
that. By the way, it runs way better from a thumb drive than from a CD.

Here is a script I use to build a grml bootable thumb drive.  You can 
set the environmental variables GRMLDEVICE and GRMLISO and just run it. 
Or you can pass them in as parameters. Or you can just run the script 
and it will ask. GRMLDEVICE is the device name of your thumb drive and 
GRMLISO is the path to a grml iso file. The script will format the thumb 
drive and then run grml2usb for you.


#!/bin/bash

test ! -z "$1" && GRMLDEVICE="$1"
if [ -z "$GRMLDEVICE" ]; then
     DEFAULT=/dev/sdb
     echo -n "Device (default=${DEFAULT}): "
     read GRMLDEVICE
     test -z "$GRMLDEVICE" && GRMLDEVICE="$DEFAULT"
fi

test ! -z "$2" && GRMLISO="$2"
if [ -z "$GRMLISO" ]; then
     for DEFAULT in grml64-full_*; do continue; done
     echo -n "GRML iso file (default=$DEFAULT): "
     read GRMLISO
     test -z "$GRMLISO" && GRMLISO="$DEFAULT"
fi
echo "Building grml on $GRMLDEVICE using $GRMLISO"

P1SIZE=2G
parted ${GRMLDEVICE} mklabel msdos
parted ${GRMLDEVICE} mkpart pri fat16 512 ${P1SIZE}
parted ${GRMLDEVICE} mkpart pri ext2 ${P1SIZE} 100%
parted ${GRMLDEVICE} set 1 boot on
sync

mkfs.vfat -n grml "${GRMLDEVICE}1"
mke2fs -L persistence "${GRMLDEVICE}2"

grml2usb --bootoptions="persistence" 
--bootoptions="mypath=/home/grml/persistent" "${GRMLISO}" "${GRMLDEVICE}1"

MOUNTPOINT=/tmp/loop
test ! -d "$MOUNTPOINT" && mkdir "$MOUNTPOINT"
mount "${GRMLDEVICE}2" "$MOUNTPOINT"
cat /dev/null > "${MOUNTPOINT}/persistence.conf"
echo "/home/grml/persistent" >> "${MOUNTPOINT}/persistence.conf"
umount "$MOUNTPOINT"
rmdir "$MOUNTPOINT"
# EOF
