Dear folks,

the `NetBSD in-kernel support for UDF' project has reached a new milestone: 
full read support for CD-RW/DVD+RW media allowing one to access a CD or DVD 
as a mountable filing system.

UDF is a commonly used filing system for CDs and DVDs developed as the 
successor of the well known ageing ISO 9660 CD standard commonly known as 
`iso' or `isofs'. UDF is commonly used in all DVD video and DVD audio 
applications as well in CD authoring programs like Nero's InCD and Roxio's 
DirectCD/Drag2Disc.

In the open-source community in-kernel support is scarce. FreeBSD has a 
read-only version that regretfully is showing some ageing and Linux has 
some read/write support for UDF though pretty restricted.

The `NetBSD in-kernel support for UDF' project tries to implement full 
read/write support for recordable and rewritable CDs, DVDs and its 
successors luke BluRay and HD-DVD.

The preliminary read-only version will most likely be committed to the 
-current tree when some unresolved issues are fixed and more media types 
are supported.

With regards,
Reinoud
