Definition

OLPC and Red Hat continually develop the Fedora-derived OLPC Linux operating system. Each day, we freeze the most up-to-date version of that OS, and make it available for download as an OS image.

Upgrades

The recommended method to update your development board or BTest system, is Autoreinstallation image. Please see that and then return here if you want a different image.

Downloads

As the operating system for OLPC is under development, there are several builds available. The latest build might not always be stable since developers are experimenting with new features. Each build is labeled with a unique version number. When reporting problems on mailing lists, please make sure you list the build number you are using.

Stable, signed builds for the XO-1 are available here:

http://download.laptop.org/xo-1/os/official/

Signed, release candidate builds are available here:

http://download.laptop.org/xo-1/os/candidate/

"Update-1" images include relatively stable builds leading up to (and including) the stable [OLPC Update.1 Software Release Notes|8.1.0 release] (build 703) and [OLPC 8.1.1 Software Release Notes|8.1.1 release] (currently build 708 is a release candidate for this release):

You can download unstable development images from:

http://xs-dev.laptop.org/~cscott/olpc/streams (look in "latest" in each stream's directory) - joyride is the primary stream, with others available for testing experimental features

And historical ones from:

http://olpc.download.redhat.com/olpc/streams/development

Latest Stable Build

A build is marked "stable" when the developers are happy with it. At minimum, it should boot successfully on A-Test boards and B-Test laptops. A stable build does not mean everything is working, nor that it is actually "stable." For example, for a while Sugar and X were both broken in a stable build, but virtual consoles worked fine and that was enough to get work done for most developers.

Casual downloaders and those upgrading to a new build beware: check the Tinderbox to see whether there are known problems before selecting a build.

The latest stable build is the highest-numbered build at [1].

Image variants

Images are available in five variants

• Normal images in the ext3/ and jffs2/ sub-directories
  • Intended for production use
  • Does not contain tools or software suitable for developers of the OLPC operating system
  • The ext3/ images are intended for USB drives (both hard drives and flash drives)
  • The jffs2/ images are intended for the on-board NAND flash.

• Developer images in the devel_ext3/ and devel_jffs2/ sub-directories
  • Contains tools useful for developers of the OLPC operating system, including: yum, rpm, vim-minimal, openssh-server, xterm, which, file, tree, wget, xorg-x11-twm, gdb packages
  • The devel_ext3/ images are intended for USB drives (both hard drives and flash drives)
  • The devel_jffs2/ images are intended for the on-board NAND flash
  • WARNING: Do not attempt to update the kernel on devel_* builds - the initrd will be wrong. We're working on fixing this through including an olpc-mkinitrd package.

• Live CD images in the livecd/ sub-directory
  • Contains an iso of a normal image which can be burned onto a cd and run by booting off the cd drive

Each variant may have available two sub-variants:

• tree: a tarball of the OS directory tree, without a filesystem
• img: a filesystem image (of one of the types described above).

Languages in which the images are available

• English
• The home Language for each participating country

Using Images

For development we offer images that run the OLPC operating system off a USB storage device. These images are located in the devel_ext3/ sub-directory, and should be used if you're unsure of which image to choose.

Passwords

Some recent builds do not permit root login. There are quite a few tickets. You can login as olpc, no password, and sudo -i instead. MitchellNCharity 14:40, 6 January 2008 (EST)

The images have no password set at build time. This means you can log in as root using no password. Always remember to change the password as the first thing when start using an image.

As the image-rpm variant ships with an SSH server you thus need to set the password to be able to login from a remote host. This is a feature of sshd.

Password handling is subject to change before official release.

Images on a USB disk

The OS images for USB disks page describes how to write these images to a USB disk, so that you can test the images on real OLPC hardware, or attempt to boot from them on your own PC.

Images on an emulator

The OS images for emulation page details how you can run an image of the OLPC operating system on a normal computer that doesn't have the OLPC hardware.

Images with the on-board NAND flash on OLPC hardware

See the Autoreinstallation image page.

Wireless

See the Wireless page for detailed instructions.

Test Group Release Notes for Images

The Test Group Release Notes page lists the "official" changelog and known problems for each build. Check that page to see if there are any known problems with the build you're installing.

User Feedback on Images

Using the User Feedback on Images page, you can see how the images worked on various systems, using various different hardware and emulator set-ups. You can also add your own reviews.

Build names and branches

Ship.1 is build 623, and was preloaded on all mass production XO machines for a while.

It isn't preloaded on new machines, and any machine with it installed should since have been updated to Ship.2. It was released around 2007-11-01. It will mostly not be seen by the outside world at all.

Ship.2 is build 650

It is the build received by Give One Get One recipients, as well as the Uruguay Ceibal project users. (Actually, Uruguay is using a slightly custom build, but it's based on Ship.2.) It was released around 2007-12-01. Read the OLPC Ship.2 Software Release Notes.

OLPC 8.1.0 (Update.1) is build 703

OLPC SW-ECO 4 - This release contains no activities, and is suitable for a base image to be customized by deploying countries using a Customization key. Release notes are available. Machines can be automatically upgraded (preserving user data) from Ship.2 to 8.1.0, although activities need to be reinstalled as they are no longer contained in the image - see the release notes.

OLPC 8.1.1 will be released in June 2008 as a minor update to 8.1.0. The current release candidate is build 708.

OLPC SW-ECO 5 - Release notes are available.

OLPC 8.2.0 is planned to be released in August 2008, current Joyride builds are progress towards it.

(No ECO yet)

Joyride builds are available at http://xs-dev.laptop.org/~cscott/olpc/streams/joyride/

"Joyride" can be thought of as synonymous with "trunk" or "HEAD" or "unstable", much like the Debian/unstable distribution.

http://dev.laptop.org/roadmap enumerates releases beyond 8.2.0

Patches

Please see the Operating_system_release_procedures for information on the patch release process.

Here is a list of the patches to date:

• OLPC 653 Software Release Notes - Ship2 patch1, 653
• OLPC 656 Software Release Notes (OLPC SW-ECO 2) - Ship2 patch2, 656
• OLPC SW-ECO 4 - "Peru and Mexico need a build for testing", so Update.1 release candidate 3 was provided as a patch.
• OLPC SW-ECO 5 - localized keyboards for Haiti and Ethiopia
