The root access documentation has some minor problems about the password:
- the mentioned command "passwd –delete root" cannot be copy/pasted: the character before "delete" is a dash ("\u2013") where it should be two hyphens ("--")
- this command indeed deletes the root password, but by doing so you actually allow anyone to connect without a password! You should not suggest that. The documentation seems to imply that this command will disable password login, but it's not the case.
