Package: dkms
Version: 2.2.0.2-1
Severity: important
Upgrading dkms drom squeeze (2.1.x.x) to wheezy (2.2.x.x) loses track of
previously built modules. This could be related to changing the
module installation location from /lib/modules/*/updates/dkms/ to
/lib/modules/*/updates/.
I discovered this during some squeeze -> wheezy distupgrade tests with
piuparts which unexpectedly left files in /lib/modules.
The following test was performed in a minimal squeeze pbuilder
environment with wheezy sources available additionally. The host is
running with the squeeze kernel, but in the pbuilder only the headers
are installed, no kernel or modules itself.
A few excerpts from the log showing the problematic behaviour, script
and full log can be found further below.
* install dkms + module-dkms from stable, build the module

- No original module exists within this kernel
- Installation
- Installing to /lib/modules/2.6.32-5-amd64/updates/dkms/
* upgrade dkms to testing
* upgrade module-dkms to testing
* first the old module gets removed ... but from the wrong location?

- Uninstallation
- Deleting from: /lib/modules/2.6.32-5-amd64/
- Original module
- No original module was found for this module on this kernel.
- Use the dkms install command to reinstall any previous module version.
* now the new one gets built and installed - but where does this
original module come from?

- Moving it to: /lib/modules/2.6.32-5-amd64/updates/
* oops, now some files are left on the system that don't belong to any
package and dkms does not think that it "owns" them.
