Sugar on a Stick/Linux/Installation

< Sugar on a Stick‎ | Linux

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 at a terminal or console command line)
    • Create a mount point directory: mkdir /run/soas
    • Mount the .iso file to make it accessible as a disk: mount /path/to/downloaded.iso /run/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.
    • With root user permissions at a terminal or console command line, use the command sudo df -Th or sudo blkid to get the USB device node name.
      • (Items in angle brackets, such as <MyAccount> are descriptive placeholders.)
       You should see something like the following: 
      [<user>@<system> <working directory>]$ sudo df -Th
Filesystem     Type      Size  Used Avail Use% Mounted on
devtmpfs       devtmpfs   16G     0   16G   0% /dev
tmpfs          tmpfs      16G   33M   16G   1% /dev/shm
tmpfs          tmpfs      16G  1.8M   16G   1% /run
tmpfs          tmpfs      16G     0   16G   0% /sys/fs/cgroup
/dev/sda1      ext4      123G   17G  100G  15% /
tmpfs          tmpfs      16G   80K   16G   1% /tmp
tmpfs          tmpfs     3.2G   10M  3.2G   1% /run/user/1000
/dev/sdb1      vfat      233G   90G  143G  39% /run/media/<MyAccount>/<filesystem label>
/dev/loop0     iso9660   942M  942M     0 100% /run/soas
      (The /run/media/<MyAccount>/ path is the standard mount point for removable media.
      /media/<MyMountPoint> is common on other operating systems.)
      [<user>@<system> <working directory>]$ sudo blkid
/dev/sda1: LABEL="Fedora30" UUID="dddf4ae0-e1fd-43c3-bacc-91acbafb3a34" TYPE="ext4" PARTUUID="000b2340-03"
/dev/sdb1: LABEL_FATBOOT="Fat" LABEL="Fat" UUID="D082-05E1" TYPE="vfat" PARTLABEL="Fat" PARTUUID="53132329-808c-4a44-adf6-e98ad17546ff"
/dev/loop0: UUID="2019-04-26-02-18-05-00" LABEL="Fedora-SoaS-Live-30-1-2" TYPE="iso9660" PTUUID="37f2045d" PTTYPE="dos"
      (Additional disk drive partitions may be listed on your computer.)
      The mount point (Mounted on), Filesystem, Size, and LABEL should help you identify what you want.
    • Unmount the USB device filesystem:
      umount /run/media/<MyAccount>/<MyUSBdiscMountPoint>
      (The /run/media/<MyAccount>/ path is the 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 the following installation command, as the root user, in one command line with many options:
    /run/soas/LiveOS/livecd-iso-to-disk --reset-mbr --overlay-size-mb 500 --home-size-mb 500 --unencrypted-home /path/to/downloaded.iso /dev/sd?1
    The '?' 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 ~960 MB, and the overlay and home size arguments, 500 and 500, were selected to fit in a 2 GB device. These may be adjusted depending on your preferences and device capacity (see LiveOS image). On a 4 GB device, one might use 1000 and 1600 for the size arguments.
     The installation transcript should look something like the following: 
    [<user>@<system> <working directory>]$ sudo /run/soas/LiveOS/livecd-iso-to-disk --reset-mbr --overlay-size-mb 500 --home-size-mb 500 --unencrypted-home /<path to>/Fedora-SoaS-Live-x86_64-30-1.2.iso /dev/sdc1

  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.

  • To create more Sugar Sticks on other 2 GB or greater USB or SD devices, while running Sugar on a Stick, one may run the Terminal Activity, and execute this command as the root user:
    livecd-iso-to-disk --reset-mbr --overlay-size-mb 500 --home-size-mb 500 --delete-home --unencrypted-home /run/initramfs/livedev /dev/sd?1
Replace /dev/sd?1 with a new device node for the second USB/SD device that you want to load with Sugar on a Stick.
