  Hello:

  Consider this example for aufs, which I'll someday manage to submit. You'=
ll
need to created an aufs package, in this case Config.in and aufs.mk

  The interesting part is aufs.mk:

------8<--------
AUFS_SITE_METHOD =3D git
AUFS_SITE =3D http://git.code.sf.net/p/aufs/aufs3-standalone

AUFS_DEPENDENCIES =3D linux
AUFS_INSTALL_STAGING =3D YES

define AUFS_BUILD_CMDS
        $(MAKE) -C $(@D) $(LINUX_MAKE_FLAGS) KDIR=3D$(LINUX_DIR) aufs.ko
endef

define AUFS_INSTALL_TARGET_CMDS
        $(MAKE) -C $(@D) $(LINUX_MAKE_FLAGS) KDIR=3D$(LINUX_DIR) install
endef

define AUFS_INSTALL_STAGING_CMDS
        $(MAKE) -C $(LINUX_DIR) $(LINUX_MAKE_FLAGS) -f scripts/Makefile.hos=
t \
                scripts/unifdef
        $(MAKE) -C $(@D) $(LINUX_MAKE_FLAGS) KDIR=3D$(LINUX_DIR) usr/includ=
e/linux/aufs_type.h
        $(INSTALL) -p -m 0644 $(@D)/usr/include/linux/aufs_type.h $(STAGING=
_DIR)/usr/include/linux
endef

$(eval $(generic-package))
------>8--------

  Mind that this is targetted for 2013.11 so it may not work that straight
forward on a more recent (or older) version.

  Notes:

  - STAGING may not be needed in your case
  - You may need to add/remove some stuff to get your case working.
  - Consider following [0] guideliness

  Disclaimer: This snippet is not an aufs fully working example.
