Same thing as happens with a real OS, you boot into something else and
try to repair things. In the case of VMs, the host can just shut the VM
down and mount it's storage. One of my use cases is developing my own
Devuan installer scripts, so I tend to do that a lot.

I intend to. This sort of thing has my own use cases, but I see Qubes is
popular enough that others have use cases where my solution would work.
