Please read these notes to understand the capabilities and known problems with a particular release of the XS ("XO School server") software. For older release notes, see XS Release Notes archived.

XS 0.7

Read steps to install.

  • Rebased onto CentOS 6.2.
  • Linux-3.2 backported from Fedora 15 for maximum hardware compatibility
  • USB install is easier than before, and is expected to be more reliable
  • Supports installation on top of existing RHEL-compatible install (e.g. CentOS), in addition to regular install media
  • Interoperates better when run on an existing network - you are no longer required to make the XS 'run' the network.
  • Networking setup greatly simplified: no more bonding
  • eth0 is now the LAN, eth1 is now WAN. This is the opposite of previous XS releases, aimed at situations where no WAN connection is available (or when running on a previously existing network).
  • Active antenna and mesh support dropped.

Known issues/untested items:

  • XS-on-XO1 not generated for this release (and XO-1 mesh is no longer supported)
  • No tested upgrade path from XS-0.6. Feedback/documentation welcome.

Notes

  • Upgrades: With this release you can now upgrade sanely from earlier version. The steps are:
    1. Recommended: Backup the system! :-)
    2. Edit /etc/yum.repos.olpc.d/stable.repo - set the 'baseurl' of the 'olpc' repo to http://fedora.laptop.org/xs/stable/olpc/xs-0.4/i386/
    3. Run yum -y upgrade
    4. You will have to re-run /etc/sysconfig/olpc-scripts/domain_config <yourbasedomain>
    5. Some new system daemons are set to start on the next restart - either restart the machine or start them manually. The services that need starting should be: incrond, apache
  • New installations: there is a bug in Anaconda which prevents it from setting the ownerships and permissions correctly in the /library directory. After installation, execute chown -R xs-rsync.xs-rsync /library/xs-rsync/{pub,tmp,state}
  • This release contains the DS-Backup implementation, with a restore facility aimed mainly at the test team. The user-friendly (and privacy-friendly) version of this will be part of Moodle - coming to a build near you soon. For production deployments you might want to disable the restore page. See documentation on this feature here.
  • This build requires a minimum of a 5.5Gig hard drive to install -- thanks to Grant Patterson for the kickstart fixes for trac 7241 .
