These are the steps for installing Sugar on a Stick on a USB/SD device.

This page is transcluded to various installation instruction pages.

  1. Download the latest Sugar on a Stick .iso file.

  2. Prepare: (with root user permissions)
    • Create a mount point directory: mkdir /media/soas
    • Mount the .iso file as a disk: mount /path/to/downloaded.iso /media/soas/
      (Where /path/to/downloaded.iso is the filesystem path, or fully specified name, of the downloaded .iso file.)
      This is the source for the installation, and must remain mounted until the installation is complete.
    • Insert a USB stick of 2 GB or greater capacity into your computer.
    • Use the blkid or df -Th command to get the USB device node name.
      •     You should see something like the following: 
      [root@MyComputer ~]# df -Th
Filesystem     Type      Size  Used Avail Use% Mounted on
rootfs         rootfs     20G  5.5G   14G  29% /
devtmpfs       devtmpfs  1.6G     0  1.6G   0% /dev
tmpfs          tmpfs     1.6G  788K  1.6G   1% /dev/shm
tmpfs          tmpfs     1.6G  1.3M  1.6G   1% /run
tmpfs          tmpfs     1.6G     0  1.6G   0% /sys/fs/cgroup
tmpfs          tmpfs     1.6G     0  1.6G   0% /media
/dev/loop0     iso9660   509M  509M     0 100% /media/soas
/dev/sdc1      vfat      995M  983M   13M  99% /run/media/MyAccount/LG
           where the mount point and filesystem sizes should help you identify what you want.
    • Unmount the USB device filesystem:
      umount /run/media/MyAccount/MyUSBdiscMountPoint
      (The /run/media/MyAccount/ path is the new, Fedora 17 standard mount point. Other operating systems may use /media/MyMountPoint.)
    • (You should have the isomd5sum package installed so that the following installation script can verify the download.)

  3. Load: Execute, as the root user in one command with arguments, the following:
    /media/soas/LiveOS/livecd-iso-to-disk --reset-mbr --overlay-size-mb 500 --home-size-mb 900 --delete-home --unencrypted-home /path/to/downloaded.iso /dev/sd?1
    where '?' in the final parameter represents the target USB device scsi drive node, such as sdb1 or sdc1, etc., and /path/to/downloaded.iso is the location and name of the .iso file.
    The operating system will occupy ~510 MB, and the overlay and home size arguments, 500 and 900, were selected to fit in a 2 GB device, but may be adjusted according to your device capacity.
          The installation transcript should look something like the following: 
    [LiveOS]$ sudo ./livecd-iso-to-disk --reset-mbr --overlay-size-mb 500 --home-size-mb 900 --delete-home --unencrypted-home /media/soas/Fedora-17-x86_64-Live-SoaS.iso /dev/sdc1

Installing boot loader
Target device is now set up with a Live image!

  4. Boot: Insert the USB stick into a bootable USB port on your computer. Set the option to "boot from USB" in your computer's BIOS setup, and then start up the computer.

  • You may create more Sugar Sticks on other 1 GB or greater USB or SD devices. In the Terminal Activity of a running Sugar on a Stick, run this command as root:
    /run/initramfs/live/LiveOS/livecd-iso-to-disk --reset-mbr --overlay-size-mb 300 --home-size-mb 175 --delete-home --unencrypted-home /run/initramfs/livedev /dev/sd?1
