When I install a new kernel, I notice that DKMS removes previous kernel modules as well as adding them to the new kernel. In the real old days these were not removed at all - so removal is a good thing. The issue is that the old kernel is still running and until machine is rebooted the modules wont be available I would think. I wonder - Is there a way to mark the deletion to happen after the new kernel is booted ? I may well be missing something of course. Installed 4.6.2 kernel while 4.6.1 running - pacman says: (1/1) Remove DKMS modules ==> dkms -q remove -q -m vboxguest -v 5.0.20_OSE -k 4.6.1-2-ARCH ==> dkms -q remove -q -m vboxhost -v 5.0.20_OSE -k 4.6.1-2-ARCH ...==> dkms -q install -m vboxguest -v 5.0.20_OSE -k 4.6.2-1-ARCH ==> dkms -q install -m vboxhost -v 5.0.20_OSE -k 4.6.2-1-ARCH ... Thanks for any thoughts. gene
