Because of the way libarchive works internally coupled with basic differences in how Joliet and RockRidge information is stored, it turns out that libarchive has to decide whether or not to use the Joliet information before it can tell whether RockRidge information is available. So preferring RockRidge is actually quite difficult. I would like to change this, but it's going to be quite a while before I have enough time to work on it. Tim
