[Pkg-dkms-maint] Bug#784127: fails to recognize installed headers from kernel-package builds

[Eduard Bloch]

Package: dkms
Version: 2.2.0.3-2
Severity: important

Repro:
$ git checkout v4.1-rc1 
$ fakeroot make-kpkg linux_image linux_headers --initrd
...
$ sudo dpkg -i ../linux-headers-4.1.0-rc1+_4.1.0-rc1-10.Local.00_amd64.deb
...
linux-headers-4.1.0-rc1+ (4.1.0-rc1-10.Local.00) wird eingerichtet ...
Examining /etc/kernel/header_postinst.d.
run-parts: executing /etc/kernel/header_postinst.d/dkms 4.1.0-rc1+ /boot/vmlinuz-4.1.0-rc1+
Error! Your kernel headers for kernel 4.1.0-rc1+ cannot be found.
Please install the linux-headers-4.1.0-rc1+ package,
or use the --kernelsourcedir option to tell DKMS where it's located

Seriously?

$ dpkg -L linux-headers-4.1.0-rc1+ | grep usr.src.lin.*h | wc -l
15074
All there! Are they ok?
$ sudo m-a build -vt --kernel-dir /usr/src/linux-headers-4.1.0-rc1+ virtualbox
(works, except for an API bug which I was just looking for)

So, what is wrong with dkms?

Regards,
Eduard.
