dkms removes kernel module when installing/upgrading

[Zé]

I have been testing dkms-2.0.16 and i can reach the conclusion that when 
upgrading a dkms package and the module kernel is the same, what dkms do,  
first installs the kernel module (as expected) but then removes it (and that 
is a total unexpected behaviour).

But ill paste here the complete output of the install/upgrade:

Good news! Module version 1.4.0 for vboxdrv.ko.gz
exactly matches what is already found in kernel 2.6.17-14mdv.
DKMS will not replace this module.
You may override by specifying --force.

-------- Uninstall Beginning --------
Module:  virtualbox
Version: 1.4.0-0.svn3059.1mde2007.1
Kernel:  2.6.17-14mdv (x86_64)
-------------------------------------

Status: Before uninstall, this module version was ACTIVE on this kernel.

vboxdrv.ko.gz:
 - Uninstallation
   - Deleting from: /lib/modules/2.6.17-14mdv/kernel/3rdparty/vbox/
 - Original module
   - No original module was found for this module on this kernel.
   - Use the dkms install command to reinstall any previous module version.


DKMS: uninstall Completed.

------------------------------
Deleting module version: 1.4.0-0.svn3059.1mde2007.1
completely from the DKMS tree.
------------------------------
Done.
+ /usr/share/rpm-helper/del-service virtualbox 1 virtualbox

The intention here is to show this terrible bug, since many times is needed to 
upgrade between releases to apply for example a patch or any other fix.

And as it can be seen the kernel module was removed, but how can that be 
possible when the intention of a dkms install/upgrade is to add/upgrade a 
kernel module in the active kernel tree?
