based on this bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=915834 It seems that setting the Temp file system to ro overly restricts access to it such that other applications (like ssh), can't function properly. That seems like a error to fix in systemd to me, but regardless we obviously cant use TempDirectory=/path:ro if its going to impact other applications like that. Instead specify a specific RuntimeDirectory that systemd can clean up for us, and modify irqbalance and irqbalance-ui to create the comms socket there.
