Actually, it probably looks more like LFS than FFS. :-)  It's been
awhile since I read up on it, but if I remember correctly, it's
essentially a log-based file system at heart.  Internally, it
resembles FFS very little.  Unfortunately, it doesn't use cluster
"fragments" like FFS does.  On the other hand, it has some very
sophisticated recovery fault-tolerant features in its design.
