Multi-CD USB stick

Well I'm not sure the title speaks for itself...
Live CDs are great and USB sticks have amazing capacities (I'm curious how it'll sound in a couple of years...)
I've bought a 6Gb USB "stick", actually it's a HD in a credit-card format.
The idea is to bring on it and be able to boot:

So I use a single syslinux with a huge configuration file.
Sometimes there are some clashes between the files of the various systems so we've to rename some when possible and choose between some when not possible.

  • syslinux.cfg and isolinux.cfg => merge all and rename some of the targets if needed
  • boot.* => choose one image (I took the Debian spiral from Etch installer) and one text (I list shortly the main targets)
  • F1..F10 help screens => choose or mix

From Etch: this is really the basis of the install, with its syslinux

  • debian-testing-i386-netinst.iso renamed as: debian.iso
  • disk.lbl
  • f1.txt .. f10.txt
  • initrd26.gz
  • initrdg.gz
  • initrd.gz
  • ldlinux.sys (install it properly as a bootable USB stick!)
  • linux
  • linux26
  • splash.rle

From DBAN (dban-1.0.7_i386.ima):

  • dbanlog
  • dbanseed
  • *.txt => dbaninfo/
  • initrd.gz renamed as: initrddb.gz
  • kernel.bzi

From Knoppix DVD:

  • knoppix/
  • balder.img
  • linux renamed as: linux-kn
  • memtest
  • minirt.gz

From FCCU:

  • knoppix/ renamed as: fccu/
  • linux renamed as: lin-fccu
  • minirt.gz renamed as: minifccu.gz (cf note)

Note: For FCCU as we had to rename the directory and as v11 is incompatible with knoppix dvd v5.1.1 I had to change minifccu.gz: 

gunzip minifccu.gz
mount -o loop minifccu /mnt/disk

Edit /mnt/disk/linuxrc and prepend the module list by the new path: (but keep the rest!) 

MODULE_DIRS="/cdrom/fccu/modules /cdrom/KNOPPIX/modules ...

And now this huge and quite messy syslinux.cfg: 

DEFAULT fccu
TIMEOUT 300

F3 f3.txt

# Note that Linux 2.4.19+ will not boot with root=/dev/rd/0.  The /dev/ram0
# name is, however, now hardcoded in 'init/do_mounts.c' so root=/dev/ram0 works
# instead.  This violates the DevFS documentation and is probably a kernel bug.

# The Boot Prompt
# ---------------
#
#  Usage: [label [kernel options] [nuke="dwipe [dwipe options]"]]
#
#  Dwipe Options:
#
#       --autonuke  Be really sure.
#    -m --method    The wipe method to use.
#    -r --rounds    The number of times to run the method.
#       --verify    The verification level.
#
#  Dwipe Methods:
#
#    dod522022m         American Department of Defense 5220.22-M standard wipe.
#    dodshort dod3pass  DoD short wipe, passess 1,2,7 from the standard wipe.
#    gutmann            Peter Gutmann's wipe.
#    ops2               RCMP TSSIT OPS-II standard wipe.
#    prng random        PRNG stream wipe.
#    quick zero         Quick erase.
#
#  Verification Levels:
#
#    0  off         Do not read anything back from the device.
#    1  last        Check whether the device is empty after wiping.
#    2  all         Check whether all passes were written properly.
#
#  Notes:
#
#    * The rounds option does not apply to to the quick method. This method
#      always runs one round.
#
#    * Use at least four rounds with the prng method. Using eight rounds with
#      the prng method is recommended.
#
#    * The last pass of every method fills the device with zeros, except the
#      ops2 method which fills the device with a random stream on its last pass.
#

# eof

Quick howto to copy the setup on another stick:

  • Copy the mbr from one to the other with sth like (check for your own drive letters!!)
dd if=/dev/sdX of=/dev/sdY bs=512 count=1
  • Check the partition table but by default you usually get one sdY1 with FAT, flag it as bootable
fdisk /dev/sdY -> a -> 1
  • Install syslinux
syslinux /dev/sdY
  • Copy the other files
