According to Policy 4.9, "invoking either of `make -f debian/rules _args..._' or `./debian/rules _args..._' must result in identical behavior." One way to inadvertently violate this policy is to use the $_ variable: $ cat debian/rules #!/usr/bin/make -f $ ./debian/rules ./debian/rules $ make -f debian/rules /usr/bin/make Currently ca. 20 packages in the archive incorrectly use constructs like $(dir $(_)) to discover directory containing source package (presumably in order to implement get-orig-source target). These packages should use $(dir $(firstword $(MAKEFILE_LIST))) instead.
