[Super-Disc: Multi-Boot Project CD/DVD Using ISOLINUX]

Add from=/bt3 to your isolinux append line. Make sure you have livecd.sgn in the bt3 folder.

Cheers

Here's some tips for multibooting other distros:

Changes to Support Multibooting Linux Live CDs on the Same Disc (14,June 2008)

This assumes that your disc label is "AdminToolkit" and that your linux directory

on the root of your disc is called LINUX. Change ISOLinux kernel and append statements as needed.

Almost all of these changes deal with editing files inside the initrd.

This file is usually a gzipped cpio or a gzipped ext2 image.

Knoppix - use the knoppix_name and knoppix_dir cheatcodes on ISOLinux initrd boot paramaters.

DSL - See Knoppix

Zenwalk - need to change name of livecd.sgn and edit liblinuxlive to change LIVECDSGN and LIVECDNAME variables

from=/LINUX/ZENWALK needs to be added on isolinux append line.

root password is ZenLive.

Fedora - Username is root, no password. initrd0.img is gzipped cpio.

To unpack: $> mkdir /home/user/tmp

$> mv initrd0.img initrd0.gz

$> gunzip initrd0.gz

$> cd tmp

$> cpio -id < ../initrd0

$> mv ../initrd0 ../initrd0_old

needed to change the sections in 'init' where it referenced the LiveOS directory.

ie.. OSMINSQFS, EXT3FS, SQUASHED. You also need to change the lines right above so

the files can be found

To pack:

$> cd /home/user/tmp

$> find . | cpio --create --format='newc' > ../initrd0.img

$> cd ..

$> mv initrd0.img initrd0

$> gzip initrd0

$> mv initrd0.gz initrd0.img

Ubuntu - need to change casper in initrd/scripts

change all $Path/casper to $Path/LINUX/UBUNTU/casper

change $mountpoint/.disk/casper-uuid to $mountpoint/LINUX/UBUNTU/.disk/casper-uuid

change all $Directory/casper to $Directory/LINUX/UBUNTU/casper

See above (Fedora) for cpio extraction and compilation.

Kubuntu - See Ubuntu

Linux Mint - See Ubuntu

OpenSuSE - need to change config.isoclient file to point new location for

openSUSE-10.3.i386*. Also need to change init and linuxrc so

that LIVECD_CONFIG points to config.isoclient in the right place.

See above (Fedora) for cpio extraction and compilation.

Mandriva - needed to modify linuxrc and change LABEL to AdminToolkit

also change /live/media/distrib.sqfs to correct path.

Clonegenius- need to change copy path in init under "Mounting Squashfs filsystem"

ISOLinux append line needs SUBDIR=LINUX/GENTOO added

CloneZilla - add /live_media/LINUX/CLONEZILLA to live_media_path_checklist in

pkg\opt_drbl.tgz\opt\drbl\conf\drbl-ocs.conf

add /live_media/LINUX/CLONEZILLA to possible_path variable in ocs-live.d/s03prep-drbl-clonezilla

add /live_media/LINUX/CLONEZILLA to possible_path variable in S99start-ocs-live in /etc/rcS.d

put changed S99start-ocs-live in the root of initrd

need to change casper in initrd/scripts

change all $Path/casper to $Path/LINUX/CLONEZILLA/casper

change all $Directory/casper to $Directory/LINUX/CLONEZILLA/casper

at the bottom (line right before the brace) create a new line and add

cp S99start-ocs-live "${rootmnt}/etc/rcS.d/"

See above (Fedora) for cpio extraction and compilation.

PCLinuxOS - need to change linuxrc in initrd (ext2 image).

Change $MNTCDROM/$BASEIMG$LOOPSEXT to $MNTCDROM/LINUX/PCLINUXOS/$BASEIMG$LOOPSEXT

Change losetup $DEVLOOP $MNTCDROM/$BASEIMG$LOOPTYPE to losetup $DEVLOOP $MNTCDROM/LINUX/PCLINUXOS/$BASEIMG$LOOPTYPE

Change all $MNTCDROM/livecd.sqfs to $MNTCDROM/LINUX/PCLINUXOS/livecd.sqfs

Kaspersky - In init change ${cdrom_mount_point}${SUBDIR}/kavresc to ${cdrom_mount_point}${SUBDIR}/LINUX/KASPERSKY/kavresc

Gentoo based.

Gentoo - In ISOLinux config change loop=image.squashfs to loop=/LINUX/GENTOO/image.squashfs

In ISOLinux config add SUBDIR=LINUX/GENTOO

Backtrack - In ISOLinux config add from=/LINUX/BACKTRACK

Virtualbox is a good way to test your changes

To get eth0 interface working in VirtualBox, you need the Bridge_Utils package:

$> brctl addbr br0

$> ifconfig eth0 0.0.0.0

$> brctl addif br0 eth0

$> ifconfig br0 192.168.1.2 netmask 255.255.255.0

Hi - I know my question is not quite right positioned here, but anyway....

I followed your instruction to build a multiboot USB-pendrive with ubuntu and pmagic located in subfolders on the stick. I am using syslinux v.3.71 and it works fine with pmagic, but with ubuntu I found no way to get it work. It starts up fine first, but then the boot-process stops on the bootscreen (with the scrollbar scrolling around) with alternating access on the USB-stick and then the CD-drive. I assume that it has something to do with the mountpoint in initrd/scripts/casper, but I have no idea what the stick's mountpoint is - I tried /media/CORSAIR already (regular mountpoint under installed Ubuntu), but that doesn't work. So any hint would be greately appreciated...
