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 .
