FEDORA based Live USB devices

Cautions with using Live USB devices

Wait for delayed writes to the USB device to finish (up to 15 seconds) before pulling it out of the system. If writes do not complete, you will corrupt the USB device file system and it will not boot.
If you do a yum update on a small USB device, you can overload the persistent overlay. [3]"Fedora 10 adds the 'reset_overlay' option that you can pass on the kernel command line which helps to recover." See LiveOS image, Talk:Downloads, & this page for more discussion of storage economics.
Use a larger device (4 GB or even 8 GB), if you plan to do updates or install new programs.
If you use a 1-GB device, do not (i) install large updates or activities or (ii) download large files. The 300-MB overlay will quickly fill up (e.g., within an hour), and your device will become corrupted (i.e., unbootable) without any warning. You may use the Sugar Cellar utility to monitor the usage of the persistent overlay. Also, check your Journal free space frequently.
Use zyx-liveinstaller Sugar_on_a_Stick/ZyX-LiveInstaller for soas-v2-Blueberry or liveinst command for Fedora based installs in a terminal to make a non-live installation. It will require about 2x as large device as the file structure will not be compressed. These non-live installs are more robust in use but may have a shorter service lifetime (See olpc:How to Damage a FLASH Storage Device.)
Fedora 13-based SoaS-Mirabelle will install with either liveinst (Anaconda) or zyx-liveinstaller Download Instructions: [4] Hint:you can also use: livecd-iso-to-disk [5] or liveusb-creator [6] [7] to create the device.
notes on ext3 / ext4 file systems:[8] (It looks like ext3 formatting may be more robust.)

dd command from terminal (non-persistent)

You will not be able to store anything on this USB. (It will be new each time you start it.)

[root@localhost Desktop]# dd  if=soas-i386-20100329.19.iso of=/dev/sd(*)
954368+0 records in
954368+0 records out
488636416 bytes (489 MB) copied, 128.247 s, 3.8 MB/s
[root@localhost Desktop]#

NOTE Important to get name of USB device correct VERY DANGEROUS IF WRONG
type "mount" in terminal and look for /dev/sd(*) ie: sda,sdb,sdc.....
It will disappear the next time you remove the target USB and enter the command again.

liveusb-creator from command line in terminal

(using Fedora 12)

a- Open terminal and type: liveusb-creator --reset-mbr

b- Move slider "Persistent Storage ( )MB" - to set size of USB Persistence file

c- Select correct "Target Device" (the USB you want to use)

d- OPTIONAL: To find your USB enter command "mount" in terminal. look for /dev/sd(x) with description of your USB

e- select the .iso file you plan to use "Use existing Live CD"

f- select "Create Live USB"

livecd-iso-to-disk script

takes a downloaded soas.iso file and writes it directly to a USB stick

Download script:[12] to your Desktop
Right click on the script file in your file manager, and change the file properties to allow executing the file as a program.
Place the source.iso file on your Desktop.
Enter command "mount" in a terminal. Look for /dev/sd(x) with a description of your device. Use the correct device node, /dev/sd?, in the script.

Hints:

Use a text editor to write the command line for the script, and review it for correctness. Then copy-paste it into the terminal. (safer)
See LiveOS image for ideas on optimizing your storage choices.
(--overlay-size-mb 800 sets size of persistence file.)
Delete this option if you want a device with non-persistent storage of changes.
Use "--overlay-size-mb 300" for 2-GB devices
Be advised about changing the device file system format in Talk:Downloads.

$ su -c "livecd-iso-to-disk --format --reset-mbr --overlay-size-mb 800 /home/xxx/Desktop/soas-i386-20100208.16.iso /dev/sdb"

Make a Soas-v2-Blueberry Installer USB (with liveusb-creator installed)

boot from Blueberry CD[13]
insert 4GB USB Target formatted fat16 or [ext2,3]

NOTE: zyx-liveinstaller must be installed in f13

(this step not required fo Blueberry)
In sugar-terminal:

su 
yum install zyx-liveinstaller

THEN:

in sugar terminal: zyx-liveinstaller

Note 1: the rest of this procedure will not work for a script created live USB [14] as CD and USB's do not show up on sugar frame.

Note 2: from terminal in sugar: yum install gvfs this fixes problem in mounting of CD and USB's in some soas versions. (from tomeu)

IF - USB and CD devices are not mounted in the bottom of the sugar frame when inserted; zyx-liveinstaller must be used

launch partitioner

/boot  ext4  200
/      ext   balance
make changes

exit partitioner (hit X in right top corner of window)

select root (/)How to Create 
select boot (/boot)
No swap hit next
install
wait until finished

exit
in sugar terminal:

su -
yum install liveusb-creator
22 files will download and install
22MB
wait until finished

exit sugar (f3) shutdown

boot new USB
insert second 2 GB USB Target formatted fat16 or [ext2,3]
Insert CD with desired soas.iso into PC
in sugar terminal: liveusb-creator --reset-mbr
graphical Fedora Live USB Creator starts:

Note: Do not use <Download Fedora> as you will fill up your USB Stick and ruin it <Use existing Live CD> <Browse>

(select from CD the .iso file)

Target Device /dev/sd(x)1 note: be sure it is correct for your USB

Set Persistent storage

(Move slider Bar) note: Max is 800 MB for 2GB USB

Press:<Create Live USB>

Verfying ISO MD5 checksum (CD will spin up)
Passed
Extracting Live Image to USB Device
Creating 809 MB persistent overlay
Installing bootloader
Complete (0.03.38)

wait until finished

exit
exit sugar (f3)/ shutdown

remove 4GB Installer USB
remove CD from CD Drive
boot new USB

Note: you can insert another USB, select it and Create another USB. This process can be repeated for multiple "virgin" copies.

I have tested this with soas-2-blueberry.iso, soas-testing-day-13-02-10.iso, and soas-i386-20100216.21.iso files

How to sugarize liveusb-creator to run it from your Soas USB

See this discussion page.

Download a non-live, ext3 File Structured, blueberry USB

A very stable alternate 4GB blueberry stick

use dd command in terminal to write to 4GB USB Download[15]Details and How-To:[16]

Note1: you may get a "not enough room on device" message when you dd this .img to a 4GB USB but but the .img is really only 3GB is size and should work.

Note2: liveusb-creator will NOT work in this USB as this in not a live system.

Note3: This is modified version of bernie's soas-2-blueberry-direct-2GB.img [17]

Notes:(revised 4/29/2010) after SugarClone Script revision

Adding Script to USB http://people.sugarlabs.org/fgrose/SugarClone

1-) BOOTED live soas USB:

in sugar root terminal:

su
cd /mnt/live/
wget http://people.sugarlabs.org/fgrose/SugarClone.

OR

2-) Live soas USB inserted and opened on another PC

download http://people.sugarlabs.org/fgrose/SugarClone to PC
Right click on Properties/Permission and check allow executing as a Program
Copy and Paste into opened USB on Desktop. (This is the /mnt/live/ directory on the USB when it is booted and running)

Make Clone Custom USB

Insert Target USB
In the Terminal Activity of that running SoaS image, enter the command:

/mnt/live/SugarClone

Script will show you what USB's are present and proceed to write to the one you select.

SugarClone script will be present on all sticks that are created by the first custom stick with all of the customizations you have done to the master.
Target USB will prompt for Name and Color on first startup as this information is not preserved.

great way to make a customized spin for special uses
