home encrypted from install (freebsd 6.1)

[Dave]

Hello,
    I'm about to do a 6.1 install on a new box. I'm separating /home in the 
filesystem so it's a system of it's own. During the install maybe after the 
install, but before the reboot i'd like to encrypt /home so that any data 
written to it after reboot will be encrypted. I was wondering if it was 
possible to do this during the install? If it is how would it effect 
programs like x? I'm going to have two users, one doing console logins, the 
other will have x whenever he logs in, i don't want the encryption to get in 
the way of this.
Thanks.
Dave.
