Dear Maintainer,
The current kernel in testing has vboxsf properly integrated and signed.
With Buster, we should use VirtualBoxGuestAdditions.iso to dkms it.
It implies linux-headers, dkms, toolchain... 300 or 400 Mio of stuff.
The integrated vboxsf is way easy to use but it currently fails for "git
clone" like work loads. Steps to reproduce :
* install debian testing in a virtualbox VM, everything as default
* configure a shared folder in virtualbox
* mount in from debian VM somewhere
* from VM, go into this folder, then :
* git clone https://a-random-non-empty-public-git-repo.git
* it fails at unpacking stage.
If host is Windows, there is 2 problems (spurious EINTR, and "File Already exists").
If host is Linux, there is 1 problem (a third one : spurious EPERM)
It's reported, patches are written by one of the person who a have took
the initiative about mainline it, I use it since some weeks locally.

Hans de Goede has submited patches to fs and char-misc teams.
On 2021-02-18 only 1/5 patches are on linux-next. Kernel fs team seems
not have pickup the 4 remaining patches yet.
I don't know if it doable to get them for buster, but it should help
everyone who tries to use this feature.
Here we use it as a way to give local development env to web developers.
Please found the patches has Hans mailed me, they should appears in
linux-next soon.
