Preferred way to do a chown on package's dirs ?

[Olivier Berger <olivier.berger@it-sudparis.eu>]

Hi.

I'm not sure I can find authoritative information on how a packager
should change the ownership (chown) of a shipped directory.

Of course this can be done in the package's postinst.

May it also be done in the debian/rules ?
For instance something like :
install: build
	dh_testdir
	dh_testroot
	dh_clean -k
	dh_installdirs
	dh_install
	install -m 750 -o www-data -g www-data -d debian/whatever_package/var/lib/mypackage/somedir
or
	chown -R www-data:www-data debian/whatever_package/var/lib/mypackage/somedir
When doing so, it seems that dpk-buildpackage -rfakeroot won't respect
that user definition (btw, that user may not exist on the machine the
package is build from, right ?).

Thanks in advance.
