Then I lost interest in udf since it works worse than cd9660 for my only application of backing up ffs file systems a file at a time, and I don't have time to fix this. (Sequential media like DVDs needs large non-vnode-based read-ahead unless the drive does it, but FreeBSD only does vnode-based read ahead. This loses especially for metadata. cd9660 metadata is smaller and more packed than udf metadata, so cd9660 loses less than udf from this.) Bruce
