Package: dkms
Severity: wishlist
Version: 2.2.0.3-1.2

Dear Maintainer,

In our derivative we provided a patched kernel.

To avoid overpatching the kernel for drivers, we provides DKMS packages,
but we have an issue with detection of newest kernel version.

The version comparaison is based on $(uname -r), if we provide a kernel
with the same number but a "lower" local part, the DKMS module is not
compiled for it, for example:

The work around is to let dkms_autoinstaller do the job: 1) install the
DKMS module, then install the kernel headers, installing both in the
same "apt-get install" invocation fails.

I made a patch to add an option to build the DKMS modules for all
installed kernels.

Regards.
