hello,

	good news are here. the story

	http://www.news.com/News/Item/Textonly/0,25,36807,00.html

	tells that SGI will release the source code of their XFS. it
lacks some features but is able to handle with files of very big size,
has b-tree layout on the media and, the most important, it is journaling
file system. if the license is acceptable I guess it will quite easy
to port XFS into NetBSD.
