-Isolate NixOS QEMU VMs from each other and from the host by using a
-squashfs for the VM's /nix/store that contains only the VM's dependencies
-(like the installer has) rather than a virtio mount of the host's entire
-/nix/store.

-**Update:** `virtualisation.useNixStoreImage` exists now! But it doesn't
-work! :( See the note in `checks/mount-grep.nix`
