Yeah, I later realised that it would be best to check for the other two magic strings in the probing function. > It would be nice to read filesystem UUID and LABEL in the probing function. The UUID isn't as straightforward as I hoped for and currently Haiku doesn't set it (see http://www.freelists.org/post/haiku-development/BFS-and-UUID,1), but LABEL is certainly doable. Will dive into the probing functions of the other superblocks and I hope I can get back to you in the near future with a second patch, implementing the probing function for BeFS. It might take a while though. :) - Jeroen -- To unsubscribe from this list: send the line "unsubscribe util-linux-ng" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
