If /etc/master.passwd is ending up with junk, that's a clue that code
that updates it isn't doing the write secondary file, fysnc it, rename,
approach.  As I understand it with POSIX filesystems you have to do that
because there is no guarantee on open/write/close that you'll have one
or the other.  Even with zfs, you could have done write on the first
half and not the second, so I think you still need this.q

Do you find that lfs is 100% solid now (in 9-stable, or current)?  I
have seen fixes and never really been sure.
