New Raspberry Pi Zero setup stalls after room-assistant installation

[dwf]

I've been slowly expanding my room-assistant cluster (up to 6 nodes now, with a 7th on the way to complete it) and after 4 nodes and a botched upgrade to 2.13 I switched to using Ansible, which has been amazing.

I have noticed one thing, which is that the first time a new Pi Zero W is provisioned by Ansible, the whole thing hangs after the room-assistant installation step. SSHing to the node in question reveals that room-assistant is installed (the launcher is available at /opt/nodejs/bin/room-assistant), there are no other SSH sessions in progress on the new Pi, and yet Ansible has failed to continue to the next step. Killing and re-running Ansible allows it to complete and bring the cluster back up.

I'm not sure exactly how to go about debugging this, and it's at most a minor inconvenience, but I thought I would document it here in case others have the same issue.
