Here's a question, though: I was under the impression that livecd-iso-to-disk *required* FAT. Also, if I were to make it ext2, would that still be turned into an 8+M filesystem? > checking.: > ---------------------------------------------------------------------------- > #!/bin/bash > # ################################### > # Author: mark roth > # Date: 30 Apr. 2010 > # Purpose: to create a working, bootable CentOS install on a USB key > ##################################### > > PATH=/sbin:/bin:/usr/sbin:/usr/bin > > if [[ $# < 2 ]]; then > echo "usage: $0 <devname> <path/to/install.iso>" > echo " Example: $0 sdb /scratch/CentOS-5.4-bin-DVD.iso" > exit 1 > fi > > if [[ ! -f /usr/bin/livecd-iso-to-disk ]]; then > echo "You must install livecd-tools before running this." > echo "See: http://projects.centos.org/trac/livecd/wiki/GetToolset" > exit 2 > fi > > if [[ -f $2 ]]; then > if file $2 | grep -q "ISO 9660"; then > echo "Using ISO image $2 ..." > else > echo "$2 is not an ISO image!" > exit 3 > fi > else > echo "$2 ISO image file not found." > exit 4 > fi > > if [[ $EUID -ne 0 ]]; then > echo "This script must be run as root." > exit 5 > fi > > if sfdisk -l /dev/$1 >& /dev/null; then > echo "Current partitions for /dev/$1:" > sfdisk -l /dev/$1 > echo -n "Press <Enter> to continue or ^C to abort: " > read aline > else > echo "No such device /dev/$1" > exit 6 > fi > > sfdisk -uM /dev/$1 << EOF > ,,83,* > ; > ; > ; > EOF > > echo "Remove and reinsert the USB key." > echo " Use Safely Remove first if in a GUI." > echo " Do not mount in GUI after reinsertion." > echo -n " Press <Enter> to continue: " > > read aline > > mkfs /dev/${1}1 > > /usr/bin/livecd-iso-to-disk --reset-mbr $2 /dev/${1}1 > > echo "USB boot media of $2 done." > > # end > ---------------------------------------------------------------------------- > Unfortunately the only system I have to test on at the moment boots the > installer OK, then asks for the installation media, but doesn't see the > USB device when Hard Disk is selected.

That's why I did it the way I did: once you get there, you tell it h/d, then point it to the second partition, that has all the rest of the USB key's space on it, and the whole .iso. mark
