This screen shows the 'file types' of the specified 'class' that will be created by processes running with '%(APP)s' type in the '%(APP)s' directory. SELinux allows policy writers to define file transition rules. These rules define the label of a newly create file system object. By default an newly created file system object will get the label of the directory the object is being created in. Creating an file in a directory with the file type of etc_t will get the label etc_t. In certain situations SELinux aware applications can override this behavior, for example the passwd command creates /etc/shadow with a type of shadow_t. A third option is for policy writers to write a transition rule. For example a process labeled NetworkManager creating content in a directory labeled etc_t will create it with the label net_conf_t. File Transition Rules can be written to create all objects of a particular class, or specific to a particular file name. You need to build a policy module if you want to add additional File Transition Rules.
