Yes. That is correct; that is what I have done. I think the empty passphrase is 
too much of a risk.

Hmmm. I'll try doing that. Is there more documentation on this somewhere? I 
want to be able to back up all my file systems. A normal user won't have all 
the permissions on them. Plus, how could I prevent this account from being 
exploited due to its passwordless nature?

Thanks,
