Subject: [PATCH] The genesis bed waits for the node to settle before asking it
 anything

Applying the packet filter restarts the container runtime a few seconds
after the installer's last push returns; a command racing that window dies
with 'No such exec instance'. Wait for the node to report applied and
current, and retry that error like the recreate it is.
