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.
As for filesystem integrity, I've occasionally not shutdown properly
and the system has subsequently come up quickly again with the
background fsck doing it's stuff.
I don't remember anybody posting to this list saying: "Help! I didn't
shutdown my machine properly and now my filesystem is toast."
At the worst you may have to run a foreground fsck.
You can set up a proper journal:
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.
