:I have seen all the messages about Softupdates, and such, and I was
:wondering what the advantages of using Softupdates are (or will be once
:the code is debugged). I have looked on the FreeBSD website, and couldn't
:find this information there.

    Softupdates basically gives you the advantage of an async mount without
    any of the risks.  It's actually better then that - it can unwind commits
    to disk before they occur ( e.g. if you create a temporary file and then
    delete it very soon after ).  Softupdates basically guarentees disk
    consistancy in the face of a crash.

    It's pretty well debugged as it stands -- I'd call it production.  I don't
    think the problem the person who was posting and calling a softupdates
    is actually a softupdates problem.  I've been using it solidly for a while
    and BEST has been using it on their nntp box ( a very heavily loaded box )
    for a few months.
