FreeBSD9 - Fresh install

[Jos Chrispijn]

I am trying to setup a new BSD server with v9.0 stable on it.
While setting it up, I come across an issue: there are some YouTube 
movies available in which only the following disk setup is chosen:
- freebsd-boot
- freebsd ufs /
- freebsd-swap
Now when I setup and choose for Auto defaults, I see the wellknown /var, 
/tmp and /usr again.
Are these differences between what I see on YouTube examples due to v9.0 
or what is causing that?

BR,
