TeX Live 2015をUbuntuで動かしています。
表題のとおり、luatexja-presetでmoga-mobo,deluxe,jis2004オプションを
使用してコンパイルすると、結果はきちんと出るのですが、
全てのフォントに関して、次のような警告と再定義（？）がログに残ります。
（テストしたソースは添付ファイルをご参照ください）
モボ／モガフォントはTTCの内部にJIS90とJIS2004にそれぞれ対応した
別々のフォントが入っているので、こうした警告が出るのは理解できるのですが、
抑制できないものかなとも思います。
警告を出さないようにする方法があるのかどうか、
あるのであればどうすればいいか、ご教示いただけるとありがたいです。
