How would I know? I was just looking for something like VirtualBox, to 
play around with a different distro. All in user space.

Now I would think twice about installing all that stuff.

As far as I remember, Synaptic did not tell me that I had installed 
something ground-breaking, or that I had to log off or reboot 
afterwards. Or are you expecting end-users to read the installation log?
