    Not currently.  At present, the SELinux security module only functions as
    a primary security module and provides minimal support for using either
    the dummy security module (traditional superuser logic) or the
    capabilities security module as a secondary security module.  The
    recommended configuration is to use SELinux with capabilities.
    
    The dummy and capabilities security modules are easy to stack with
    SELinux because they do not use the security fields LSM added
    to the kernel data structures.  Stacking the SELinux module with any
    module that does use these fields will require the definition of a
    common security object header with a module identifier and a link
    for chaining multiple security objects on a single security field.
    This has not yet been a priority for us.
