[feature-request] please make GuestVM additions setup modular

[Technologov]

I would like to ask to make GuestVM additions setup modular, so one could install only single component of the whole bunch. Both for Windows & Linux guests.

It will make solution more scalable & easier to debug & more configurable to the user.

So user could install separately:

-Video driver -Mouse integration driver -Time synch with Host -Idle CPU -...

I might not always want to have full integration. For example, one component may be buggy, so I will still work with other components.

Such as in case: ​http://www.virtualbox.org/ticket/41

In other scenarios, I might want to have a different date on my guest PC than Host PC for application testing purposes. (So I want to disable only this part of guest integration, rather than disable integration fully.)

In Linux this is already possible. Start the installer with one of the following options:

all -- install all components of the Guest Additions
kernel-module -- only install the core components in the Linux kernel
vfs-module -- install the shared folder component
timesync -- install the time synchronisation component
x11 -- install guest drivers for the X Window System

The kernel module will always be installed if you install one of the other components. You can use several of these options at one time.

I will update the documentation to contain these options.
