of course having the kernel modules as part of the distribution is what
users want and need. The only reason why we didn't ask the distribution
maintainers is that we have frequent updates on the module source code
so we suggest to always have the same version of the kernel modules and
VirtualBox installed. VirtualBox a.b.c will usually not work with the
kernel modules x.y.z. Sometimes this works but there is no guarantee.
As we do frequent updates of VirtualBox we need to ship the kernel module
source as part of our VirtualBox package.
I'm aware that this should be much easier for you as you decide yourself
when to upgrade to a newer VirtualBox release. In that case you upgrade
both, the kernel modules and the VirtualBox package and it works.
