Red Hat ENTERPRISE LINUX 5 - DEPLOYMENT Deployment Manual page 501

Adding a New User
Select a login shell. If you are not sure which shell to select, accept the default value of /bin/bash.
The default home directory is /home/<username>/. You can change the home directory that is
created for the user, or you can choose not to create the home directory by unselecting Create home
directory.
If you select to create the home directory, default configuration files are copied from the /etc/skel/
directory into the new home directory.
Red Hat Enterprise Linux uses a user private group (UPG) scheme. The UPG scheme does not add or
change anything in the standard UNIX way of handling groups; it offers a new convention. Whenever
you create a new user, by default, a unique group with the same name as the user is created. If you
do not want to create this group, unselect Create a private group for the user.
To specify a user ID for the user, select Specify user ID manually. If the option is not selected, the
next available user ID above 500 is assigned to the new user. Because Red Hat Enterprise Linux
reserves user IDs below 500 for system users, it is not advisable to manually assign user IDs 1-499.
Click OK to create the user.
