By the way, this file talks about (1) "using"/"userspace"/"embedder"
subproject holding 'appliance/', and toplevel (master) holding toplevel
Makefile, or (2) 'using' subproject holding both 'appliance/' and toplevel
Makefile with the help of --exclude. 

Another option would be to have only "embedded"/"used"/"requirement" be
subproject holding 'kernel-2.6', and 'appliance/' hold by toplevel (master)
commit.  Perhaps not the best solution for 'kernel + userspace tools'
example, but might be better workflow for 'application + library' or
'application + engine' example.
