Jessie's kernel 3.16 should have full UDF support by the code in: https://github.com/torvalds/linux/tree/64aa90f26c06e1cb2aacfb98a7d0eccfbd6c1a91/fs/udf fs/udf/Kconfig points to Documentation/filesystems/udf.txt which says "Write support requires a block driver which supports writing. Currently dvd+rw drives and media support true random sector writes, and so a udf filesystem on such devices can be directly mounted read/write." man 8 mount mentions some "Mount options for udf". A few weeks ago i was able to mount a Nero-made pure UDF image. Have a nice day :) Thomas
