Can anyone point me to some good LFS (Log-structured File System)
documentation?  I've searched Google, but it only returns some ancient
papers.  

I think I understand the basics of its design and its benefits, but I'm
not sure about e.g. its impact on disk space.  Doesn't LFS require much
more diskspace, since it keeps the entire history of your files on-disk?
