Linux Change Default User Home Directory

Linux Change Default User Home Directory While Adding A New User B y default base directory for the system user is set to /home directory. I'd like to add user to /iscsi/home/${user} directory instead of the default /home. How do I force useradd command to add user to /iscsi/home under CentOS / RHEL / Fedora Linux server? Default values for account creation defined in /etc/default/useradd file under CentOS / RHEL / Fedora / Debian / Ubuntu and other Linux distros. Simply open this file using a text editor, type:   # vi /etc/default/useradd The default home directory defined by HOME variable, find line that read as follows: HOME=/home Replace with: HOME=/iscsi/user Save and close the file.
