== System Administration Tools for the ARM Build Farm ==
+
== Update the raspberrypi-config package ==
  
−
The [[Fedora ARM Koji Buildsystem]] or "farm" consists of 23 ARM builder systems which will grow to 38 by the end of this semester. As it grows, the need for efficient system management tools increases. The previous semesters' students started the work of setting up [http://www.nagios.org/ nagios] (monitoring) and [[https://fedorahosted.org/func/ func]] (group control) tools.
+
The raspberrypi-config package contains the default configuration files for Pidora. These files need to be updated to reflect new options available in the Raspberry Pi firmware, as well as options that are not commonly used and may conflict with common use-cases - for example, the current configuration files cause kernel start-up messages to be reported on the serial port. This is rarely used, any may cause conflicts with other devices connected to that port (e.g., LCD displays).
  
−
This project involves configuring these tools to work with all of the systems in the ARM build farm, as well as setting up and configuring the [http://www.puppetlabs.com/ puppet] (configuration management) tool.

== Koji Hub on ARM ==
+
Expected result: An updated, working raspberrypi-config package
  
−
The [[Fedora ARM Koji Buildsystem]] system uses [[CDOT_Development_Systems#Machine_names.2C_IPs.2C_and_Status|HongKong]], an x86_64 system, as the [[:fedora:Koji|Koji]] hub, along with a group of [[Fedora ARM Secondary Architecture/ARM hardware|ARM builders]].
+
== Kernel Configuration Files ==
  
−
Ideally, it would be nice to prove the ability of the Fedora-ARM project to be entirely self-hosting by using an ARM system as the Koji hub (this is sometimes called "Eating your own dogfood" in the industry). This project involves configuring the [http://www.globalscaletechnologies.com/t-openrdcdetails.aspx OpenRD-Client] system as Koji hub and determining if this is a viable configuration.
+
The build process for the kernel uses a configuration file to control which kernel capabilities are built into the kernel itself, which are built as loadable modules, and which are not built. The Pidora kernel configuration file is a combination of the RaspberryPi default configuration file and the Fedora configuration file. This project involves reviewing the Pidora kernel configuration to optimize it for the widest possible range of use-cases while ensuring a fairly small kernel image size.

== Device Support and Testing: PandaBoard ==
+
Maximum number of participants: 1
  
−
Various ARM devices need different driver sets and/or kernels. This project will test the Fedora-ARM system on the [http://pandaboard.org/ PandaBoard], creating a kernel that works well with it, and figuring out how to use as many of the built-in peripherals as possible.

== Add PandaBoards to the Fedora-ARM Build System ==
+
RPM/YUM appear to perform slowly on the Pi -- which is appropriate, since the Pi has a slower processor and storage system than most modern PCs -- but the performance can probably be improved. This project involves profileing the RPM/YUM operations to determine which parts of the processing are slowest, and then examining how those parts work to see if any improvements in speed are possible.

−
We have 15 [http://pandaboard.org/ PandaBoards] on order for the [[Fedora ARM Koji Buildsystem|Fedora-ARM build farm]]. These machines need to be configured and added into the farm, and then optimized to build packages as quickly as possible.
+

== iSCSI/AoE Support * ==
+
== Internationalization Support in Firstboot for Pidora 19 ==
  
−
[http://en.wikipedia.org/wiki/ISCSI iSCSI] (SCSI over TCP/IP) and [http://en.wikipedia.org/wiki/ATA_over_Ethernet AoE] (ATA-over-ethernet) are different SAN protocols that can be used on a standard ethernet network.[[Fedora ARM Secondary Architecture/iSCSI|iSCSI did not work reliably in Fedora 12 on ARM systems]], but will be needed by future ARM server systems. AoE has not been well-tested on ARM systems.
+
This project involves taking the Pidora 19 Firstboot package and internationalizing it (making it possible to use multiple language files with Firstboot). Note that Pidora 19 is expected to use a Fedora 18-style Firstboot system (as was used in Pidora 18) rather than the firstboot system used in Fedora 19 and higher.
  
−
Goals of this project:
+
Skills required: python, i11n using gettext, packaging
−
(1) iSCSI and AoE need to be tested for stability and performance.
 
−
(2) The ARM builders, which currently use loopback-mounted filessystems on top of NFS, should be reconfigured to use iSCSI or AoE (whichever is the optimal solution) providing it is faster than the current solution.
 
  
−
* Maximium number of students: 2
+
Maximum number of participants: 1
−
* Skills required: Linux system administration, debugging and troubleshooting, kernel building, benchmarking, documentation writing
 
−
* Resources: an ARM system, CDOT PC systems
 
−
* Expected result: iSCSI on ARM fixed and tested, and changes pushed upstream; AoE tested on ARM; report comparing iSCSI and AoE performance on ARM; ARM buildsystem configured to use a high-performing iSCSI or AoE storage solution in place of the existing NFS system

== CreateRepo Performance Improvements * ==
+
Expected result: A version of firstboot and the firstboot modules that are fully internationalized
  
−
The [[Fedora ARM Koji Buildsystem|Fedora-ARM build farm]] consists of the koji-hub/koji-web system (on [[CDOT_Development_Systems#Machine_names.2C_IPs.2C_and_Status|HongKong]], an x86_64 machine) and a group of ARM builders. HongKong also handles the [http://createrepo.baseurl.org/ CreateRepo] tasks, which heavily load that machine. It might make sense to move those tasks to another machine, but doing so makes the CreateRepo jobs take a lot longer (15 minutes on HongKong vs. 55 minutes on another x86_64 server). This is presumably due to the overhead of sharing files between HongKong and the other server over NFS on the 100 Mbps Seneca network.
+
== New Firstboot for Pidora 20 ==
  
−
This project involves figuring out how to run the CreateRepo jobs more quickly. Possible solutions include a 1 Gbps LAN, a redistribution of the file storage or a change to a different file storage technology, or optimizing the CreateRepo tasks on HongKong for best speed.
+
Firstboot on the Pi varies a bit from firstboot on PCs, because the software isn't installed onto storage in the same way as PCs. This project involves updating the Fedora 20 firstboot package to work with Pidora 20.
  
−
* Maximum number of students: 1
+
Skills required: python programming, packaging, testing
−
* Skills required: system administration, benchmarking
 
−
* Resources: CDOT server systems (HongKong, Ireland, Scotland)
 
−
* Expected result: significant reduction in CreateRepo times, especially when multiple CreateRepo tasks are running

== RPM-based Kernels for Fedora ARM * ==
+
Maximum number of participants: 1
  
−
On PC architecture systems (x86_64 and i386), Fedora manages and updates kernels as RPM packages, which modify [http://www.gnu.org/software/grub/grub-legacy.en.html grub] boot parameters and the initial ram disk ([http://en.wikipedia.org/wiki/Initrd initrd],  configured by [[:fedora:Dracut|dracut]]).
+
Expected result: A version of the Fedora 19 or Fedora 20 firstboot that works on the Pi and has full support for the Pidora options (such as rootfs resizing)
  
−
On Fedora-ARM systems, the kernel is not managed via RPMs, grub is not used, and the initrd system is rarely used.
+
== Compiler Flags on Pidora ==
  
−
This project involves understanding how the PC (i386/x86_64) kernel/boot/initrd system works, determining which pieces can be reused on Fedora-ARM and which pieces need to be adapted or replaced, and implementing RPM-based kernel management for ARM.
+
We're not sure if the compiler flags being used for Pidora are optimal. This project involves building a number of packages with different combinations of compiler flags, observing the results (in terms of binary size and performance) and recommending the optimal set of flags.
  
−
* Maximum number of students: 3
+
Skills required: building, benchmarking
−
* Skills required: Linux system administration, script writing, RPM packaging, kernel building, initrd debugging
 
−
* Resources: an ARM system
 
−
* Expected result: RPM-based Kernels work on Fedora-ARM, with changes committed upstream; documentation about the differences between kernel management on ARM and on PCs
 
−
* Initial contacts: [[User:Chris Tyler|ctyler]], [[User:Paul.W|PaulW]]
 
  
−
== Fedora-ARM Communication * ==
+
Maximum number of participants: 1
  
−
We're not doing a great job of communicating how the [[:fedora:Architectures/ARM|Fedora-ARM]] project is doing, especially how [http://arm.koji.fedoraproject.org current builds] are progressing. The [http://arm.koji.fedoraproject.org/status status page] is very bare-bones and doesn't convey a lot of information, the Fedora-ARM wiki pages (on the [[:fedora:Architectures/ARM Fedora]] and [[:Category:Fedora_ARM_Secondary_Architecture|Seneca]] wikis) need to be made more useful to prospective users, and we need an effective communication strategy with the rest of the [http://fedoraproject.org Fedora community]. This project involves writing some web scripts to create a easy-to-use, informative status page (showing, for example, the current state and progress of the ARM builds), creating user documentation on the Fedora wiki, and fostering effective communication within the Fedora-ARM project and the larger Fedora community.
+
Expected result: Modified RPM macros that include the optimal flags for Pidora
  
−
* Maximum number of students: 2
+
== Avahi Configuration for Pidora ==
−
* Skills required: Apache administration, script-writing, effective written communication skills
 
−
* Resources: the web server on HongKong, various data sources within the Fedora-ARM build system, Fedora project communication tools, access to ARM systems
 
−
* Expected result: a useful (easy-to-use, informative) and automatically-updated Fedora-ARM status page; improved user documentation on the Fedora wiki (e.g., how to set up Fedora-ARM on common devices); better communication on the arm@lists.fedoraproject.org mailing list and the #fedora-arm IRC channel
 
−
* Initial contacts: [[User:Chris Tyler|ctyler]], [[User:Paul.W|PaulW]]
 
  
−
== Automatic ExclusiveArch Addition/Removal * ==
+
Avahi (zeroconf) enables discovery of computers without DNS or IP numbers. This project involves configuring Avahi for use on the Pi, so that other computers can connect to it by name without DNS support. This configuration must then be packaged in such a way that it can be included in the Pidora composes without causing conflicts.
  
−
RPM packages may be specified as being suitable only for particular architectures through the use of ExclusiveArch and [http://www.rpm.org/max-rpm/s1-rpm-inside-tags.html#S3-RPM-INSIDE-EXCLUDEARCH-TAG ExcludeArch] tags in the spec file. If a base package, such as a language (interpreter or compiler) or a library does not build on a particular architecture, then dozens or hundreds of other packages cannot be built. These packages should all be marked as ExcludeArch in the upstream git package repository. Later, if that base package is updated to work on that arch, the ExcludeArch lines will need to be removed.
+
Skills required: testing, packaging
  
−
This project involves writing a script that will mass-add or mass-remove ExcludeArch tags (or, if those tags exist, add or remove a particular architecture), pushing the changes to the upstream [[:fedora:Using_Fedora_GIT|git repo]].
+
Maximum number of participants: 1
  
−
* Maximum number of students: 1
+
Expected results: A configuration package that, when installed, will correctly set up Avahi for local discovery on the Pi
−
* Skills required: scripting (Python and/or bash), packaging
 
−
* Expected result: a script that will do mass adds/removals of ExcludeArch tags given a list of packages

== Fedora-ARM Package Building and Troubleshooting ==
+
== Upstream the Pidora RPM Changes ==
  
−
The [[Fedora ARM Secondary Architecture|Fedora-ARM]] project is building Fedora 13/14/15 for the ARM architecture. As this proceeds, various problems arise. For example:
+
There are some small changes to the RPM system that have been done for Pidora. These changes need to be included in the upstream version of RPM. This project involves working with upstream to ensure that these changes are in the correct format and included in subsequent releases of RPM.
−
* Some packages fail to build for ARM. They can be fixed up to build successfully on ARM, or if that's not possible, marked as unsuitable for ARM ([http://www.rpm.org/max-rpm/s1-rpm-inside-tags.html#S3-RPM-INSIDE-EXCLUDEARCH-TAG ExlcudeArch]).
 
−
* If a group of packages is built to work with a specific version of a library, and a newer version of that library replaces the older version, then the packages that rely on that library can break. This can often be remedied simply by rebuilding the broken package; in other cases, patches are required.
 
  
−
Note that one package build issue will often block many other packages.
+
Skills required: interpersonal skills - negotiation, patch creation, packaging
  
−
This project involves working with other members of the Fedora ARM build team to resolve package build problems and get F13/F14/F15 released for ARM as soon as possible.
+
Maximum number of participants: 1
  
−
* Maximum number of students: 4
+
Expected results: Pidora RPM changes will be upstreamed
−
* Skills required: packaging, troubleshooting
 
−
* Expected result: problems with the Fedora-ARM builds are cleared as quickly as possible; F14-ARM released by the end of the semester

+
Fedora 20 includes support for the Wayland display system. The RaspberryPi foundation has been working on a Wayland implementation for the Pi. This project involves getting the two to work well together.
  
−
Mozilla Sync is a technology for synchronizing personal data (bookmarks, passwords, form values, and cookies) across multiple machines. It uses a server known as [https://wiki.mozilla.org/Labs/Weave/Sync/1.0/Setup Weave].
+
Skills required: system administration, debugging, possibly some programming, packaging
  
−
This project involves packaging Weave for Fedora and getting it through the [[:fedora:Package Review Process|package review]] process. (Why package the Weave server? So that people can run a private version, either for enhanced security or for testing).
+
Maximum number of participants: 2
  
−
* Maximum number of students: 1

== Package Hadoop ==
+
== Automate Pidora Kernel and Firmware Building ==
  
−
[http://hadoop.apache.org/ Apache Hadoop] is a set of tools used for large-scale distributed computing. It would be great to get this packaged for Fedora.
+
The Raspberry Pi Foundation maintains a kernel fork that is updated frequently. We would like to package kernel and firmware changes on a daily basis, and have these available in a testing repository so that anyone can use them. Periodically, we will select a kernel-firmware combination from this testing repository and make it available as the main Pidora kernel.

== Package the WIX Toolchain * ==
+
Maximum number of participants: 1
  
−
[http://wix.sourceforge.net/ WIX] is an open-source packaging system for Microsoft Windows software. It is used to prepare software packages that can be installed on a Windows machine. However, the WIX tools themselves can run on Linux, which is useful for cross-development (writing software on Linux for use on Windows, e.g., the virt-manager utilities for Windows virtual machine guests).
+
Expected results: Raspberry Pi kernel and firmware updates will be included in a package in a testing repository through an automated (cron'd) process
  
−
This project involves packaging WIX for Fedora and getting it through the [[:fedora:Package Review Process|package review]] process.
+
== Change raspberrypi-vc Package to Build from Source ==
  
−
* Maximum number of students: 1
+
Originally, the VideoCore IV GPU on the Pi was used with proprietary libraries which were only available in compiled form, so the raspberrypi-vc package was originally set up to package prebuilt binaries and not build from source. The source code for these libraries is now available, and the raspberrypi-vc package should be changed to build from source (this will help with SELinux compatibility).
−

== Repository Setup for Mozilla Nightlies and Betas * ==
+
Expected result: A visually appealing boot screen, packaged as a drop-in replacement for the current boot screen
  
−
Many web developers want access to the latest Firefox pre-releases, including the nightly builds and beta releases. Mozilla's build team wants to make these accessible as parallel-installable binaries, released through a Fedora-compatible repository. Last semester, a group of SBR600 students set most of this up; this project involves extending and improving their work.

The rootfs-resize package resizes the Pidora rootfs after installation. It works with primary partitions, and it works with the NOOBS system, but it doesn't work with a NOOBS-style layout outside of NOOBS (i.e., where the rootfs is placed in an extended partition). This project involves extending rootfs-resize so that it can resize extended and logical partitions as well as primary partitions.

== Packaging Pi-compatible Software ==
  
−
It would be good if we could create scripts that told a machine how to generate an optimized build, a debug build, unit tests, talos runs, locale repackages.
+
There are a number of Pi-specific software packages that could/should be included in Pidora. Select one, package it, and get it into Fedora (preferred) or directly into Pidora.
−
If you look in the [http://hg.mozilla.org/build/tools/file/tip/scripts tools/scripts] repo you can see that we have a simple shell file to do this for the fuzzing automation. The buildbot factory that calls it is called [http://hg.mozilla.org/build/buildbotcustom/file/a70b38b40088/process/factory.py#l7895 ScriptFactory] and it is very simple.

We have a hundred jobs running per hour and we sometimes have jobs that have to wait for something before getting started. If we optimized the load we could use the build resources more effectively. I will be adding bugs to this [http://www.themoviemind.com/wp-content/uploads/2008/08/chuck-norris-2.jpg tracking bug] to reduce our load on our pools and therefore reduce our waiting times.

Introduction

This is a list of potential projects related to the SBR600 course that need people.

Students: Please select a project that you're interested in and add an entry to the project table/participants page.

Open Source Community Members: We welcome your recommendations for potential projects. Please create an account on this Wiki and create a description for your proposed project below. Please list your contact info (just an IRC or FAS2 name is OK) as well as links to any related web pages as Resources for the proposed project. (Questions? Ask Chris Tyler).

Notes

Each project listing contains a general description, plus this information:

  • Maximum number of students - Do not exceed this number without approval from your professor.
  • Skills required - This is a rough list of some of the skills required for this project. This list may be incomplete or inaccurate, but it will give you a starting point in evaluating whether this project is a good fit for you. It is not assumed that you will have all of these skills at the outset of the project -- some of them will be picked up as you do the project.
  • Resources - An initial list of computer and information resources to get started on the project.
  • Expected result - A rough indication of what is expected at the conclusion of the project.

You will have an opportunity to investigate, expand upon, and fine-tune this information as you prepare your initial project plan. For example, you may come up with a more detail list of expected results (deliverables), resources, and contacts during your planning.

Individual Deliverables
Note that when multiple people are working on the same project, they will have independent deliverables -- it's not really group work, but rather separate, closely related projects.

Sample Project

This is a sample project stub. You can use the template for Sample Project in order to create a project page for one of the projects listed below. This is how you 'sign-up' for a project.

NOTE: if someone has already created the project page, speak to this person and see if you can join them. If so, simply add your name to the Project Leader(s) section on the project page. Otherwise, you can become a contributor later.

Raspberry Pi Fedora Remix Projects

Update the raspberrypi-config package

The raspberrypi-config package contains the default configuration files for Pidora. These files need to be updated to reflect new options available in the Raspberry Pi firmware, as well as options that are not commonly used and may conflict with common use-cases - for example, the current configuration files cause kernel start-up messages to be reported on the serial port. This is rarely used, any may cause conflicts with other devices connected to that port (e.g., LCD displays).

Skills required: packaging

Maximum number of participants: 1

Expected result: An updated, working raspberrypi-config package

Kernel Configuration Files

The build process for the kernel uses a configuration file to control which kernel capabilities are built into the kernel itself, which are built as loadable modules, and which are not built. The Pidora kernel configuration file is a combination of the RaspberryPi default configuration file and the Fedora configuration file. This project involves reviewing the Pidora kernel configuration to optimize it for the widest possible range of use-cases while ensuring a fairly small kernel image size.

Skills required: kernel configuration/building, packaging

Maximum number of participants: 1

Expected result: An improved kernel configuration in the raspberrypi-kernel package

Profile and Improve RPM and YUM performance on the Pi

RPM/YUM appear to perform slowly on the Pi -- which is appropriate, since the Pi has a slower processor and storage system than most modern PCs -- but the performance can probably be improved. This project involves profileing the RPM/YUM operations to determine which parts of the processing are slowest, and then examining how those parts work to see if any improvements in speed are possible.

Skills required: profiling, programming, packaging

Maximum number of participants: 1

Expected result: Either a report proving that RPM/YUM are as fast as can be expected on the Pi, or changes to affected packages to improve performance

Internationalization Support in Firstboot for Pidora 19

This project involves taking the Pidora 19 Firstboot package and internationalizing it (making it possible to use multiple language files with Firstboot). Note that Pidora 19 is expected to use a Fedora 18-style Firstboot system (as was used in Pidora 18) rather than the firstboot system used in Fedora 19 and higher.

Skills required: python, i11n using gettext, packaging

Maximum number of participants: 1

Expected result: A version of firstboot and the firstboot modules that are fully internationalized

New Firstboot for Pidora 20

Firstboot on the Pi varies a bit from firstboot on PCs, because the software isn't installed onto storage in the same way as PCs. This project involves updating the Fedora 20 firstboot package to work with Pidora 20.

Skills required: python programming, packaging, testing

Maximum number of participants: 1

Expected result: A version of the Fedora 19 or Fedora 20 firstboot that works on the Pi and has full support for the Pidora options (such as rootfs resizing)

Compiler Flags on Pidora

We're not sure if the compiler flags being used for Pidora are optimal. This project involves building a number of packages with different combinations of compiler flags, observing the results (in terms of binary size and performance) and recommending the optimal set of flags.

Skills required: building, benchmarking

Maximum number of participants: 1

Expected result: Modified RPM macros that include the optimal flags for Pidora

Avahi Configuration for Pidora

Avahi (zeroconf) enables discovery of computers without DNS or IP numbers. This project involves configuring Avahi for use on the Pi, so that other computers can connect to it by name without DNS support. This configuration must then be packaged in such a way that it can be included in the Pidora composes without causing conflicts.

Skills required: testing, packaging

Maximum number of participants: 1

Expected results: A configuration package that, when installed, will correctly set up Avahi for local discovery on the Pi

Upstream the Pidora RPM Changes

There are some small changes to the RPM system that have been done for Pidora. These changes need to be included in the upstream version of RPM. This project involves working with upstream to ensure that these changes are in the correct format and included in subsequent releases of RPM.

Skills required: interpersonal skills - negotiation, patch creation, packaging

Maximum number of participants: 1

Expected results: Pidora RPM changes will be upstreamed

Wayland

Fedora 20 includes support for the Wayland display system. The RaspberryPi foundation has been working on a Wayland implementation for the Pi. This project involves getting the two to work well together.

Skills required: system administration, debugging, possibly some programming, packaging

Maximum number of participants: 2

Expected results: The Wayland snapshot in Fedora 20 will be usable on the Pi (Ideal: fully packaged; Acceptable: Instructions on how to set it up)

Automate Pidora Kernel and Firmware Building

The Raspberry Pi Foundation maintains a kernel fork that is updated frequently. We would like to package kernel and firmware changes on a daily basis, and have these available in a testing repository so that anyone can use them. Periodically, we will select a kernel-firmware combination from this testing repository and make it available as the main Pidora kernel.

Skills required: scripting (python and/or bash), packaging

Maximum number of participants: 1

Expected results: Raspberry Pi kernel and firmware updates will be included in a package in a testing repository through an automated (cron'd) process

Change raspberrypi-vc Package to Build from Source

Originally, the VideoCore IV GPU on the Pi was used with proprietary libraries which were only available in compiled form, so the raspberrypi-vc package was originally set up to package prebuilt binaries and not build from source. The source code for these libraries is now available, and the raspberrypi-vc package should be changed to build from source (this will help with SELinux compatibility).

Skills required: packaging

Maximum number of participants: 1

Expected result: A new version of the raspberrypi-vc package that build from source, is compatible with the current Pidora package, and can be easily updated/maintained

Write an Updated Boot Screen

Pidora includes an OpenGL-powered boot screen, which uses the Raspberry Pi Fedora Remix logo. The current code does not use OpenGL very effectively.

This package should be updated to use OpenGL better and to use the Pidora logo.

Skills required: C programming, OpenGL programming, packaging

Maximum number of participants: 1

Expected result: A visually appealing boot screen, packaged as a drop-in replacement for the current boot screen

Update rootfs-resize

The rootfs-resize package resizes the Pidora rootfs after installation. It works with primary partitions, and it works with the NOOBS system, but it doesn't work with a NOOBS-style layout outside of NOOBS (i.e., where the rootfs is placed in an extended partition). This project involves extending rootfs-resize so that it can resize extended and logical partitions as well as primary partitions.

Skills required: Python scripting/programming, system administration, packaging

Maximum number of participants: 1

Expected result: An updated rootfs-resize package

Packaging Pi-compatible Software

There are a number of Pi-specific software packages that could/should be included in Pidora. Select one, package it, and get it into Fedora (preferred) or directly into Pidora.

Idea.png
Finding Your Own Package
You can find any Pi-specific software and propose packaging it for your project. Note that it must be (a) broadly-useful Pi-specific software, or (b) a substantial software package that would be generally useful in Fedora and specifically on the Pi, in order to be approved as a project.

Some possible packages ideas to get you started:

  • Adafruit WebIDE
  • Adafruit libraries/tools/etc (select a specific piece of software)
  • OMXplayer
  • Vidcore library compatibility package (symlink farm in /opt/vc so that source code expecting to find the VC libraries there will work successfully)
  • Quick2wire python library

See the Pidora Bug Tracker for ideas for other packages that people want included in Pidora.

Skills required: packaging

Maximum number of participants: 1 per package (identify the package!)

Expected result: A working, Pidora-compatible package that has gone through package review

Clean Up the Pidora Kickstart File

The Pidora images are composed using a kickstart-based process. The kickstart file could be cleaned up for better readability and smallest-functional package selection.

Recent (but not necessarily latest) kickstart: http://scotland.proximity.on.ca/raspberrypi/test-releases/rpfr18v6/latest/pidora-18.ks

Skills required: packaging, composing

Maximum number of participants: 1

Expeccted result: A clean kickstart file for Pidora 19

Infrastructure Projects

Bug Tracker for Pidora

Pidora currently uses a Trac instance for bug tracking. However, there is a lot of spammer activity on that system. Implement an effective spam prevention system on Trac, or implement an alternative bug tracking system such as Bugzilla. Document the solution for future maintainability.

Skills required: system administration, documentation

Maximum number of participants: 1

Expected result: A spam-resistant bug tracking system

Create a Fedpkg-compatible Package Repository for Pidora

Fedpkg is a tool used to manage Fedora packages using GIT (and http). We'd like to be able to use it for Pidora-specific (non-Fedora) packages as well. To set up Fedpkg, a package database (pkgdb), GIT repository, http repository, and Fedpg configuration will be required. Completion of the various components of this project should result in a usable, RPM-installable Fedpkg configuration for Pidora packages.

Skills required: system administration, testing, packaging

Maximum number of participants: 3

Expected result: A working Fedpkg repository, plus configuration files packaged up in an RPM

Mirrorlist CGI Script

Yum uses a mirrorlist retrieved from a server to determine which mirrors to use for downloading packages. This mirrorlist can be generated by a script (e.g., to randomize or to optimize mirror selection), but at the present time a static file is just passed through to the yum client.

Skills required: scripting, testing

Maximum number of participants: 1

Expected result: An updated mirrorlist script
