On Linux, you could theoretically compile just that module without installing all of Guest Additions, but it’s a dependency nightmare. The ISO contains the source, so it’s possible with make in the src/vboxsf/ directory. Would you like a deep dive into any specific part — like how the 3D acceleration works, or building the additions from source for a custom kernel? Useful for automated VM provisioning (e
