What happens if you try to log in as root, or to 'go root' (by e.g.
running 'su' in a terminal)?
Does it error out directly, or can you log in as root by pressing Enter
without typing anything (i.e., giving a blank password)?
The former would be (as previously mentioned) a crazy system design, and
the latter would be a fairly serious security issue IMO - even for a
system intended to be used by only one person.
The usual architecture of "no root password" is, as I understand it,
"root's entry in the password database contains a value which cannot
possibly be the hash of a password", meaning that you can't directly log
in as root.
This is usually coupled to the first normal user account created being
given a very generous entry in /etc/sudoers.
