This is [[Harmonic_Distribution/Deployment|one of possible]] reference implementations of [[Harmonic Distribution]] based solutions. The goal is creating Sugar based downstream distribution to run on OLPC XO laptops.
This is [[Deployment_Platform/Deployment|one of the possible]] reference implementations of [[Deployment Platform]] based solutions. The goal is creating a Sugar based downstream distribution to run on OLPC XO laptops by end-users. The created reference implementation is intended to be a template for final deployment distributions.
== Try ==
== Overview ==
To try reference implementation on an XO laptop, download one of prebuilt images and proceed below instructions to flash it. Note that images were built using recent development version of software. So, images might be used to easily test recent changes.
The task is to create an XO image capable of further support.
The image will be composed using the [http://wiki.laptop.org/go/OSBuilder olpc-os-builder] utility and will be populated with the following content:
'''System packages'''
:Packages will be installed from the following sources:
:* stock Fedora repositories,
:* [http://mock.laptop.org/cgit/ stable OLPC repositories],
:* one of the [[Template:Sweets_Distribution_Linkbar|Sweets Distribution]] repositories (for now, only the [[Platform_Team/Sweets_Distribution/Factory|Factory]] repository is available),
:* the [[#Deployment_repository|deployment repository]] to keep packages specific to a particular deployment.
'''Initial Sugar Activities'''
:[[Deployment Platform]] based solutions are based on [[Sugar Network]], which makes all Sugar Activities accessible from a local school server or an Internet located one. Nonetheless, it is useful to have some first-time activities already included with the image.
: Activities will be downloaded from the Sugar Network and placed in the {{Code|~/Activities}} directory in the image.
'''Deployment configuration'''
:This is how final systems will be initially configured and supported afterwards. All deployment configuration is placed in a [[#Deployment_package|meta package]] in the [[#Deployment_repository|deployment repository]]. This meta package contains dependencies and configuration files for all other packages needing to be installed on final systems. Further, if there is a need to change the configuration on already installed systems, the meta package will be updated and spread among users.
== Start new implementation ==
These are step-by-step instructions on how to create a new deployment distribution based on this reference implementation.
=== Deployment repository ===
Make sure that the Fedora repository is accessible from the building host and end-users. If you are looking for a building and hosting environment, try [[Platform_Team/Open_Build_Service|packages.sugarlabs.org]], which is an instance of [http://www.open-build-service.org/ Open Build Service].
If you are using [[Platform_Team/Open_Build_Service|packages.sugarlabs.org]], create a new project, and add the Fedora 14 repository from the [[Sweets Distribution]] project your implementation is based on. For example, there is {{OBS/project|SweetsDistribution:Factory:ReferenceXO|reference project}} based on {{OBS/project|SweetsDistribution:Factory|SweetsDistribution:Factory}} repositories.
=== Deployment package ===
Use the [http://git.sugarlabs.org/platform/reference-xo reference package] as a template. Copy its source and tune it for local needs. Look for comments to gain a better understanding.
The reference package is structured as follows:
* {{Code|etc/}}<br>These files will be copied as-is. Place here all configuration files you need to support afterwards.
* {{Code|post.d/*.sh}}<br>These files will be executed right after installing package. Place here routines that can't be represented by configuration files.
* {{Code|image/}}<br>olpc-os-builder files to [[#Create_images|create XO images]].
* {{Code|Makefile}}<br>Handy makefile to create sources tarball.
* {{Code|deployment.spec}}<br>RPM spec file to create package.
This is the only package that will be installed implicitly after including the {{Code|sweets}} olpc-os-builder module. Thus, add to the {{Code|deployment.spec}} all dependencies that final systems will require. Note that there is no need in installing Sugar Activities or their dependencies; these routines will be handled automatically after setting the {{Code|offline_activities}} option in the olpc-os-builder configuration file.
Put sources in the new git project and commit them.
To create a package tarball, call the command
make dist
If you are using [[Platform_Team/Open_Build_Service|packages.sugarlabs.org]], call the [http://en.opensuse.org/Build_Service/CLI osc] utility to upload newly created sources tarball and spec file to OBS.
=== Create images ===
First of all, [[Sweets_Distribution#Add_repository|attach]] the proper [[Sweets Distribution]] repository, and install the {{Code|olpc-os-builder}} package from there. This package is different from upstream; it contains additional modules (see {{Code|image/*.ini}} files for details).
Then, go to the {{Code|image/}} directory and call one the the following commands to create images:
olpc-os-builder --additional-defaults common.ini xo-1.ini
olpc-os-builder --additional-defaults common.ini xo-1.5.ini
Consult olpc-os-builder's [http://wiki.laptop.org/go/OS_Builder home page] for more information.
=== Post-install support ===
Post installation support is all about updating packages in the [[#Deployment_repository|deployment repository]], e.g., update the configuration in the [[#Deployment_package|deployment package]]. Then, using one of the [[Deployment_Platform/Deployment#Scenarios|deployment scenarios]], distribute the package updates among users.
{{Anchor|Try reference implementation}}
== Try a reference implementation ==
To try a reference implementation on an XO laptop, download one of the prebuilt images and proceed with the instructions below to flash it. Note that images were built using a recent development version of the software. So, images might be used to easily test recent changes.
Reference XO images might not be up-to-date (since there are not intended to be used as-is by deployments), so, run full system update right after flashing to make sure that system is recent:
sudo yum update
