This requires knowing version release date. If you want that version, the date used should be one or two days before that version's release date. Repacking is important! Nevertheless, you need to go to Git ML and ask why repacking is required in that case (I have tried searching threads there, but inconclusive). > +The make target olddefconfig and the ``yes "" |`` used when utilizing > +localmodconfig will set any undefined build options to their default value.
