Without changing the SELinux label for private /dev of a service, it will take a generic file system label: system_u:object_r:tmpfs_t:s0 After this change it is the same as without `PrivateDevices=yes`: system_u:object_r:device_t:s0 This helps writing SELinux policies, as the same rules for `/dev` will apply despite any `PrivateDevices=yes` setting.
