When I was going through the document step by step, I found that it would be a good thing to either mention not to set a passphrase for the host key generation or just add the -N "" option for the host key generation to avoid accidental setup of a passphrase for the host keys rendering them unusable to sshd.
I am uncertain about the < /dev/null redirect. I have tested it ssh-keygen still outputs stdout to the shell.
Or was there another reason for this to be there?
