possibly could, but it escaped me as to how. And before I do- I

shutdowns/battery dead on the laptop- I also have 500G which is a
while to wait for fsck. Speed I'd like, but I have to consider
system integrity first.
I'm unfamiliar with the new bsdinstaller but AFAIK it sets up a UFS2
filesystem for you.
This comes with background fsck and softupdates which achieve the
objective of not having to wait for a lengthy foreground fsck if you
don't shutdown your laptop cleanly.
but to be honest, I wouldn't bother in your position: it's just more
stuff to go wrong for no appreciable gain to you.
9.0 also supports soft-update journalling which eliminates the
background fsck.
If you don't know whether it's on or not you can run
tunefs -p /
If it's not on then tunefs can turn it on, but you will presumably need
to reboot into single user mode.
So how does soft-update journaling compare to gjournal? I'm using
gjournal now and it runs a bit of a dog, but it is reliable (until
another ufs filesystem turns up at boot) and necessary in my
environment. Can I dump it for this new one?
Its used on a laptop with heavy load on the disk, the power on the
battery can run out too quick for batterymon to shut it down- plus kids
that play silly monkeys with daddy's laptop... :)
