Other neat uses for the modified_livecd-iso-to-disk script

Case 1-non-live USB/SD

  • Make second live USB from iso downloaded with wget to root of your USB/SD

(I used Bernie's Blueberry-Direct ext3 non-live real file system, expanded with gparted to fit a 8-GB SD card)

http://people.sugarlabs.org/Tgillard/soas-2-blueberry-direct-cleared-3GB.img.xz  (modified and expanded version)

Downloaded to root: 

wget http://alt.fedoraproject.org/pub/alt/nightly-composes/soas/soas-i386-20100411.16.iso  (latest)
[root@localhost ~]# ./modified_livecd-iso-to-disk soas-i386-20100411.16.iso /dev/sd(*)1    *(see note below)

Case 2-Copy files to your Live USB

  • Copy-paste/drag-drop soas-i386-20100405.17.iso (or any soas .iso) to an opened 2-GB live USB while it is mounted in a PC (as a USB storage device, not booted).
    (This is the same location seen when the USB is booted and one is looking at the /mnt/live/ directory in the Sugar Terminal activity.)
  • Copy-paste modified_livecd-iso-to-disk to the same location.
Reboot from USB
  • reboot a computer from this USB device and proceed to write it to another 2-GB USB device:
    Here is an alternate method to obtain the script file:
    In the Terminal Activity, change the working directory:
cd /mnt/live
wget http://people.sugarlabs.org/fgrose/modified_livecd-iso-to-disk
chmod +x modified_livecd-iso-to-disk
Make new USB
cd /mnt/live/
./modified_livecd-iso-to-disk soas-i386-20100405.17.iso /dev/sd(*)1

NOTE: /dev/sd(*)1 (the 1 is important)

type mount to find your USB device name

Works fine.... It should work with any live cd.iso

Obsolete?

This page appears to be rather stale.... is any of it still current? :)
