I have virtualbox, virtualbox-additions, virtualbox-extpack-oracle, virtualbox-modules emerged, but I have not been doing a @module-rebuild because I removed the 3 vbox modules from /etc/conf.d/modules because I don't currently run it (if I need another VM I'll do the @module-rebuild, manually modprobe, etc).
But at boot time the system keeps wanting to load the modules (and is failing since I have not rebuilt them for the current kernel). How do I get the system to quit trying to autoload the Virtualbox modules (vboxdrv, vboxnetadp, vboxnetflt)?
