• They appear out-of-order
• They are have newlines at the end
• The cut-off at 128 characters is too short for some messages
• They all appear to be reported as [Warning]

So the out-of-order thing is the most annoying obviously, but it might also be responsible for the quick boot time we now see (takes about 2 seconds for cud to boot instead of the usual 6-7 seconds).

Currently the client sends logs with QoS 1, but even if I switch to QoS 2, the message order isn't getting better.

Even if I put a 5-second timeout on publishing log messages, which should make the publishing wait for each message being published before the next one is processed, does not seem to have an effect. Weird, especially that it worked perfectly in-order with MQTTPubSubClient before... 🤔
