[Pkg-dkms-maint] Bug#763534: dkms mkdeb makes dubious assumptions about permissions

[Russ Allbery]

Package: dkms
Version: 2.2.0.3-1.3
Severity: normal

The file /etc/dkms/template-dkms-mkdeb/Makefile, which I believe is
used by dkms mkdeb, makes rather dubious assumptions about permissions
in the module source.  In particular, it contains the following rule:

ifeq ("$(wildcard $(NAME)-$(VERSION))", "$(NAME)-$(VERSION)")
        install -d "$(SRC)"
        cp -a $(NAME)-$(VERSION) $(SRC)
        chmod 644 -R "$(SRC)/$(NAME)-$(VERSION)"
endif

That chmod will remove executability from any probe shell scripts,
configure scripts, or any other supporting infrastructure in the
package, which results in build failures.
