Fedora 11 Games Spin

Summary

To provide a Fedora Games Spin (live dvd) as part of the Fedora 11 release

Owner

• Name: Bruno Wolff

Current status

• Targeted release: Fedora 11
• Initial kickstart file exists in the spin-kickstarts package in F10.
• Three games have been identified for removal.
  • starfighter - Removed from Fedora because of license issues.
  • vdrift - Only works with binary blob video drivers which won't be on the games spin DVD.
  • uqm* - uqm-data was removed removed from Fedora because of license issues and is 100+ MBs of data that would need to be downloaded before the game could be played.
• The base kickstart has been changed from fedora-live-base to fedora-livecd-desktop to get a display manager.
• Test iso images are being produced using F10 + Updates + Updates-testing that work with casual testing. Initial rawhide testing shows the squashfs file system will be just over 4GiB and require using udf instead of iso9660.
• Space is very tight. Some packages from fedora-livecd-desktop may need to be removed or livecd-creator may need to be changed to work with a squashfs file system over 4 GiB. The latter would add over 300 MB of compressed space while still fiting on a DVD.
• Several games packages are missing dependencies for their scripts. These are being tracked in bugs:
  • 475915 (ularn)
  • 475919 (nethack-vultures)
  • 475921 (vodovod)
  • 475924 (rogue)
  • 475925 (nethack)
  • 475928 (powermanga)
  • 475929 (freedoom)
  • 475931 (fillets-ng)
  • 476162 (freedroidrpg)
  • 478721 (escape)
• I am also seeing an error with the solar plymouth plugin scripts.
• I am going to need help testing as I won't be able to personally fully execute all of the steps in the test plan below.
• Percentage of completion: 70% (based on most of the work having been composing the game list that was done before I started working on the feature).

Detailed Description

Fedora 8 had a games spin, which unfortunately was not maintained for Fedora 9. There were problems building it for Fedora 10 that were not resolved in time for the release. This is an attempt to revive this spin for Fedora 11.

Benefit to Fedora

I think a games spin is more likely to get people to try it out than most other spins. As such it makes it a nice candidate for one being handed out at events focusing on introducing people to Fedora. While the games are not going to be impressive for hard core gamers, there is a nice variety that is likely to have something of interest for most people. A liveusb version of the spin could be even better as that allows people to play their games on other people's computers while keeping their saved games and high score lists with them.

Scope

• We will include many games that are not installed by default in the desktop spin. Since the total set of games will not fit on a single DVD, we will try to include the more polished games available, including those that require 3D graphics support and network play.

• I only plan on testing an i586 version of the spin.

• Trying to allow for builds with a squashfs file system greater than 4GiB (~4.3GB). (4.7GB is the capacity for the common formats for DVD burners using 12cm disks.) This will be done by making changes to livecd-creator to choose a format (iso9660 or udf) based on the size of the squashfs file system image.

Test Plan

• Release alpha and beta releases in sync with Fedora 11

• Test that the Applications->Games menu has the correct subcategories

• Test that each game starts when run from the Application->Games menu

• Test a sample of 3D games to ensure that they work on supported 3D hardware (How do we get coverage of the various video cards?)

• Verify that sound (music, sound effects) work in a sample of games

• Verify that network games work with the livedvd networking out of the box (I may not have an easy way to do testing of this feature.)

• Verify that automatic screen mode switching works for games in fullscreen mode (I may not have access to a machine with kernel mode setting enabled for purposes of this testing.)

• Verify that using the new feature of livecd-creator works on the vast majority of systems. This should be done even if the games spin seems to be small enough not to need it as the space requirements are very close to the limit and updates in parts of Fedora not directly related to this feature could bump it over very late in the process. A simple way to go over 4GiB is to uncomment the entries for uqm* and vdrift.

• Verify that live installs work both with and without udf being used.

• Verify that live usb devices with persistent storage still work with udf. I may need help with this test as currently I don't have a USB device with more than 4GB on it. That may change before the F11 release though.

User Experience

A similar experience to the default desktop spin, except that the Applications->Games menu will be populated with a large number of games split into subcategories.

Dependencies

• This spin depends on a working -desktop and/or -xfce spin.

• There is not a lot of interdependency between the individual games, so the final list of games that will be included will likely continue to change as new games are added before F-11 is released.

• Changes to other parts of Fedora may raise the size of the spin enough to require needing a new feature of livecd-creator or dropping of packages from the spin (either from the desktop spin or games).

• Getting an OK from the Spin SIG to produce DVD Spins with a squashfs file system over 4GiB even though the spin still fits on a DVD. As this requires using UDF instead of iso9660 and could potentially prevent some people from using it. (I don't know if machines that can boot off of pure iso9660 DVDs, but not UDF ones are common.)

Contingency Plan

• Don't include a spin

Documentation

• We can provide a list of all of the games included in the spin, but will not include a description and documentation for each and every game. Some brief documentation of some games is being maintained at https://fedoraproject.org/wiki/Games

Release Notes

• Ditto as documentation
