As Martin pointed out, LFS sounds good in theory but turns out not to be that good in practice. That said, there's nothing stopping someone pulling sys/ufs/lfs out of the Attic. The retirement comment states that it was suffering from bitrot even before 3.0 so there's probably a non-trivial amount of work needed to get it going again. On the positive side, many of the people who worked on it are still around so anyone wanting to resurrect it could probably find reviewers who knew the code. Personally, I'd prefer to see the effort applied to getting journalling to work with UFS2. -- Peter Jeremy
