virSecurityManagerDomainSetPathLabel is used to make a path known to the security modules, but today is used interchangably for - paths to files/dirs to be accessed directly - paths to a dir, but the access will actually be to files therein Depending on the security module it is important to know which of these types it will be. The argument allowSubtree augments the call to the implementations of DomainSetPathLabel that can - per security module - decide if extra actions shall be taken. For now dac/selinux handle this as before, but apparmor will make use of it to add a wildcard to the path that was passed.
