Some problems about Oracle Virtualbox 5.0.14 r105127

[fyb]

I installed Oracle Virtualbox 5.0.14 r105127 following the official guide yesterday.
But when i tried starting virtualbox today(that means,after a reboot),i met an error message box,which said that vboxdrv wasn't loaded.
I followed the prompts of the message box and ran '/sbin/rcvboxdrv setup',but the argument 'setup' wasn't supported by '/sbin/rcvboxdrv' at all.
I've solved the problem by running '/etc/init.d/vboxdrv setup' following some information on a forum.But I'm curious about why vitualbox "cheated" me...
I guess there is some problem with it.Maybe it will "cheat" more people.So how can I inform developers?

(I'm sorry but I'm not from a English-speaking country so my English is not very good.)

I have no idea what you think is the official guide, so perhaps it would be better to be explicit about which guide you mean.

I'm by no means a Linux host expert, but did you install VirtualBox for the correct user on your host?
