The existing version.txt is kinda annoying. The common case of referring to the current version requires joining three values and the names of those values only make sense in ChromeOS. Instead just use version as a string, using VERSION, VERSION_ID, and BUILD_ID just as they appear in os-release. It is up to the few scripts that need the individual parts to break the version apart. The old values remain for the sake of compatibility.
