Volume and File Structure for Write-Once and Rewritable Media
using Non-Sequential Recording for Information Interchange
</a></p>
<p>FreeBSD has an implementation of the UDF filesystem
but it is quite aged and doesn't support many features from newer UDF
revisions (&gt;=2.01), it's also readonly.
NetBSD implementation by Reinoud Zandijk supports most of UDF features
and has write support too. Initial port could be readonly so that
at least newer pre-authored media (e.g. BD) is accessible.
Porting write support is a bit trickier.
