Detailed Description

Benefit to Fedora

Upgrade method which does not rely on Anaconda. And allow to provide upgrade method with nearly zero downtime.

Scope

Test it on all supported platforms and probably on Secondary Arches as well.

Test it with different comps groups installed (Desktop, web server...)

How To Test

Download https://raw.github.com/xsuchy/fedora-upgrade/master/fedora-upgrade to machine with Fedora 17 and run it. You should end up with Fedora 18. Check if everything is correct.

User Experience

Upgrade without interruption of service. Only interrupted for aproximately 50 seconds needed for reboot.

Upgrade script is bash script, which is for power user like receipt. So if somethings breaks, admin can easily continue by investigating script - unlike anaconda or dracut, which is black box.

Dependencies

None.

Contingency Plan

There is bunch of upgrade methods: PreUpgrade and Anaconda Installer. None of them conflicts with FedoraUpgrade. And if there will be problem with FedoraUpgrade we can easily rollback to PreUpgrade and Anaconda Installer.
