Understand that the LFS was something completely different than the filesystems we've just been discussing (journaled filesystems, or filesystems with intent logs). The rotting LFS was a log filesystem wherein a linear log of changes made were kept. This gave a performance boost to operations that were large and sequential, as it avoided the work UFS goes through on a write to extend a file (all the stuff about dealing with fragments and trying to keep all the extents of a file in the same cylinder group). Handy, I suppose, to record streaming video. You probably knew that, didn't you. -crl -- Chad R.
