How to make a USB flash drive function as a Ubuntu (or Kubuntu, Xubuntu, Edubuntu) Live CD. The base file system is ext3, it boots using extlinux and supports the same hardware as the Live CD. Instructions on how to update the Live CD and modify it's contents are also given. For the entire document /dev/sda is the USB device.

Introduction
 
  
−
Booting from a USB device is ofter faster than from CD and USB drives are easier to carry. You should know why you want and or need this. We used Kubuntu 7.04 Feisty Fawn as our image for booting and a Gentoo system for building on.
 
−
Making the LiveUSB
 
  
−
Download a copy of the latest Ubuntu ISO, at this time Feisty, store that ISO some place. Ensure that you have squashfs-tools, initrd-tools and syslinux packages installed. We will re-partition and format the USB device, copy the LiveCD contents over and tune it up with extlinux.

−
Re-partition and format the USB drive. Ensure that the first partition is at least 1GiB in size and marked bootable. Any remaining space can be divided as necessary. When formatting choose ext2, do not put a journaling filesystem onto the USB device.

Modifying or Updating the Image
 
  
 
The filesystem is stored in the squashfs image and is therefore not open for direct update. Below we will mount the image, copy the contents out, chroot into that environment and perform necessary actions.

Pada bagian ini akan di jelaskan bagaimana cara membuat USB flashdisk agar berfungsi seperti LiveCD Ubuntu. File system yang digunakan adalah ext2, dia akan dibooting menggunakan extlinux dan mendukung hardware yang sama seperti LiveCD asalnya.


Persiapan

  • Siapkan Ubuntu ISO yang terbaru.
  • Partisi dan format USB flashdisk anda.
$ fdisk /dev/sdX
$ cfdisk /dev/sdX
$ sudo mkfs.ext2 /dev/sdX1

Mount partisi & file ISO 

$ sudo mkdir /mnt/usb_disc
$ sudo mount /dev/sdX1 /mnt/usb_disc
$ sudo mkdir /mnt/live_cd
$ sudo mount -o loop ubuntu-9.04-desktop-i386.iso /mnt/live_cd

Copy isi livecd ke usb flashdisk 

$ cd /mnt/live_cd/
$ cp -aR casper dists install pool preseed .disk /mnt/usb_disc

Membuat extlinux

kita tidak perlu mengcopy isi informasi isolinux karena kita akan menggunakan extlinux 

$ cd /
$ mkdir /mnt/usb_disc/extlinux
$ extlinux -i /mnt/usb_disc/extlinux

Sekarang edit file config /mnt/usb_disc/extlinux/extlinux.conf agar berisi kira-kira sbb, 

DEFAULT /casper/vmlinuz
APPEND  file=preseed/kubuntu.seed boot=casper initrd=/casper/initrd.gz ramdisk_size=1048576 root=/dev/ram0 rw quiet splash --


Mengubah dan mengupdate isi dari ISO

The filesystem is stored in the squashfs image and is therefore not open for direct update. Below we will mount the image, copy the contents out, chroot into that environment and perform necessary actions. 

$ mount -o loop -t squashfs /mnt/usb_disc/casper/filesystem.squashfs /mnt/ubuntu_usb
$ mkdir /tmp/ubuntu_usb_image
$ cp -aR /mnt/ubuntu_usb/* /tmp/ubuntu_usb_image/
$ mount -t proc none /tmp/ubuntu_usb_image/proc
$ mount -o bind /dev /tmp/ubuntu_usb_image/dev

Lakukan chroot sesudah semua siap 

$ chroot /tmp/ubuntu_usb_image /bin/bash

Now that we are in the new environment it can be modified in almost any possible way.

apt-get install aircrack-ng firefox kismet exit

Once finished then re-package the directory into a squashfs image. 

$ cd /tmp
$ mksquashfs ubuntu_usb_image ubuntu_usb.squashfs
$ cp ubuntu_usb.squashfs /mnt/usb_disc/casper/filesystem.squashfs

USB flashdisk siap untuk digunakan
