Manage default home directory permissions with adduser vs. useradd

[Preston Hagar]

You could just stick with adduser:

# adduser --shell /bin/false --gid <GID_OF_users> --gecos 'Fantasio'
fantasio

As another alternative, edit  /etc/login.defs   which is the config file
for useradd

and set

UMASK 027

which should give you 0750 permissions on the users home directory when you
create it with the useradd command.
