I wish, but it doesn't appear to be that way in practice. Either I misunderstand the requirements for CD filesystems, or this is where the "If your burning software fully supports UDF..." caveat comes into play. When I try to make a UDF CD-R in Nero it insists on truncating the filenames to 64 characters in order to make them Joliet compatible. I yell back "I don't care about Joliet, I'm trying to make a UDF filesystem! Just leave my filenames alone!", but it ignores my entreaties.
Apparently Joliet compliance checking is still being activated even though I selected a UDF filesystem. Whether this is a bug or is required for UDF on CDs, I don't know. I don't have a DVD burner so I can't verify how it behaves when burning DVDs.
