useradd --help
-d, --home-dir HOME_DIR home directory for the new user account
-M, do not create user's home directory
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 ?
Thank you.

What result do you expect to get? Every user needs a home directory in /etc/passwd even if it doesn't exist. Regards, Dennis

OK, I can use -d /nix but what should -M actually do ? -- Regards, Paul. England, EU. Je suis Charlie.
