update application for instantOS
incremental updates. Arch has a tendency to break when not updating for a long time. Packages and operations are tested only so far as that they don't break on new installations or actively maintained ones. Installations that are in a state that nobody has tested in months or years can break when "skipping" intermediate updates. Keeping old update scripts around and executing them one after another until the current version is the newest one solves this problem, as the update script only gets executed on the version it was intended for.
If the update script relies on packages that don't exist anymore, it will fail.
