Hi,
i recently was in the same situation that i had to install additional
files.
You sure to not need sudo there. The permissions and ownership will be
set and controlled by the package manager.
You want to make sure the Makefile of your modules installs everything
with "make install" or "make modules_install" and then override the
rules template to call the modules Makefile directly ... not the
default.
my_module_0.1.bb:
...
SRC_URI += "file://debian/my_rules.tmpl"
...
do_my_rules() {
mv ${WORKDIR}/debian/my_rules.tmpl ${WORKDIR}/debian/rules.tmpl
}
addtask my_rules after do_unpack before do_transform_template
...

See this discussion and patches

With this the Makefile of the out-of-tree module can now do all sorts
of fun stuff in "modules_install" and "install". And you patch the
sources of that module to contain a Makefile that does what you want.
