As Bodo Eggert said, "-o norock" helps. In fact, I've hit two "bugs": 1. blkid is unable to recognize HFS+ISO9660 CD. Just tracked it down and fixed only to find that it was aleady fixed: http://git.kernel.org/?p=utils/util-linux-ng/util-linux-ng.git;a=commitdiff;h=791a2fd67c118c3f07141e4cc95532fe908015a9 2. some kernel feature - when Rock Ridge is present on iso9660, it's preferred over Joliet. The CD contains both but seems that only Joliet has files inside? When it's mounted with "-o nojoliet,norock", it's empty too. Can we detect this case and avoid it somehow (switch to Joliet?) -- Ondrej Zary -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
