## Policy for user domains ####################################### ## ## The template containing rules common to unprivileged ## users and administrative users. ## ## ##

## This template creates a user domain, types, and ## rules for the user's tty, pty, home directories, ## tmp, and tmpfs files. ##

##

## This generally should not be used, rather the ## unpriv_user_template or admin_user_template should ## be used. ##
