+\fImkhomedir_helper\fR
+is a helper program for the

+module that creates home directories and populates them with contents of the specified skel directory\&.

+The default value of
+\fIumask\fR
+is 0022 and the default value of
+\fIpath\-to\-skel\fR
+is
+\fI/etc/skel\fR\&.
+.PP
+The helper is separated from the module to not require direct access from login SELinux domains to the contents of user home directories\&. The SELinux domain transition happens when the module is executing the
+\fImkhomedir_helper\fR\&.

-The pam_mkhomedir PAM module will create a users home directory if it does not exist when the session begins\.

The skeleton directory (usually
-\fI/etc/skel/\fR) is used to copy default files and also set\'s a umask for the creation\.
