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.
