QA:Testcase RpmOstree Rebase

Description

A simple validation test case for rebasing to other versions of Fedora IoT.

Setup

This testcase can be run on either an image or installation, on hardware or in virtualization.

How to test

List available branches (note, Fedora 29 and 30 may be listed but not supported):

$ sudo ostree remote refs fedora-iot

fedora-iot:fedora/devel/aarch64/iot
fedora-iot:fedora/devel/armhfp/iot
fedora-iot:fedora/devel/x86_64/iot
fedora-iot:fedora/rawhide/aarch64/iot
fedora-iot:fedora/rawhide/armhfp/iot
fedora-iot:fedora/rawhide/x86_64/iot
fedora-iot:fedora/stable/aarch64/iot
fedora-iot:fedora/stable/armhfp/iot
fedora-iot:fedora/stable/x86_64/iot

Rebase to the stable branch (if testing stable rebase to rawhide):

$ sudo rpm-ostree rebase fedora/stable/$(uname -m)/iot

Once completed, reboot into the branch:

$ sudo systemctl reboot

Verify that the rebase was successful:

$ rpm-ostree status
State: idle
AutomaticUpdates: disabled
