It depends on what you mean by ‘conflicts’. In general any update that is not a full-image update will result in a state, which is no longer fully tracked by the original image that you installed. If you mean, that this is possible with Mender, without breaking the device, then yes. Directory updates can also support rollback. Which means, that if something goes wrong during the install, the module will clean up after itself. Not though, that this also means, that no single update-artifact no longer contains the entire state of the system on your running device. For this a full image install is needed
Does this make sense?
