: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.
