Yes, it’s a known limitation.

I was thinking we could have the VM talk to the host daemon socket:

  guix system vm config.scm --share=/var/guix/daemon-socket

However that doesn’t work, I suppose 9p doesn’t support forwarding
sockets.

The other option would be to make /gnu/store a writable overlayfs, which
should allow us to run a local guix-daemon with its own store in the VM.
