There is no write support in UDF in FreeBSD.  When I wrote the fs code,
packet writing was the only way to do discrete writes, and it's very
hard to make that work with a traditional VM system.  Now with DVD+R,
it's probably worth someone's time to look at it (though the append-only
nature of +R means that there are still some nasty VM complications to
deal with).  Until that happens, mkisofs can be used to create a static
UDF filesystem.
