Automatic installation problem

[Tarasov Alexey]

Hello!

I'm trying to make full automatical FreeBSD installation. I have the 
following lines in my install.cfg:

> command="echo sshd_enable="YES" >> /etc/rc.conf"
> system
> command="echo 'pass' | /usr/sbin/pw useradd -u user -h 0 -G wheel"
> system

But during installation I get some error messages:

 > DEBUG: dispatch: calling resword 'system'
 > echo sshd_enable=YES >> /etc/rc.conf: not found

I am using FreeBSD 6.0-RELEASE.
