Boxes in the default install

[Colin Walters]

Hi,

So I know like many problems this type of thing will go away once
gnome-software is a useful mechanism to install applications and we
don't need to have a massive pile of apps in comps, but:

It's really catastrophic to install Boxes by default in virtual machines
because it drags in libvirt which sets up a guest network at the default
192.168.122 mask which means your networking doesn't work until you
either reconfigure the host or the guest:

So...Boxes seems specialized enough to be a secondary installation.  Can
we do that, since the alternative is dubious hacks at the libvirt level?
