Emulating Netgear R8000 issue

[WizardsOfTheInternet]

I have managed to get the router launching when using ./run-emux-docker, running launcher and then selecting my newly created Netgear R8000 device.

I have an issue when I run the emux-docker-shell command, run userspace and then select /bin/sh. I get the following error:

[emux-docker 🐚] ~$ userspace
Entering Netgear R8000 Wi-Fi Router CONSOLE (/bin/sh)
mount: mounting /proc on /emux/R8000/rootfs/proc failed: No such file or directory

chroot: can't execute '/.emux/emuxshell': No such file or directory
Connection to 192.168.100.2 closed.

What else am I meant to do to be able to get this running?
