yet useradd -M -s /sbin/nologin FRED

produces in /etc/passwd

 fred:x:504:504::/home/fred:/sbin/nologin

Trying again with

 useradd -d /dev/null -s /sbin/nologin doris

gives a CLI message

 useradd: warning: the home directory already exists.
 Not copying any file from skel directory into it.

and in /etc/password

 doris:x:505:505::/dev/null:/sbin/nologin

QUESTION

What is the 'official' method of creating a user with no home directory and no log-on ability ?

Your first invocation seemed to look fine. What result do you expect to get? Every user needs a home directory in /etc/passwd even if it doesn't exist.
