Jackd stopped working -- yet again

It took a lot of sleuthing and experimentation, but I got jackd working. That was in February or so. But sometime in March, it stopped again. As a result, I’m stuck in a generation that I built at that time. It builds fine (usually – I’m on unstable), it just flat out won’t run. I have the logs if anyone would like to seem them. But trust me, they’re not very revealing.

So, any generations since that time, jackd fails to run, but it continues to run with the same config for the old March generation.

Has anyone else been able to maintain a system with a working jackd since that time? Has something changed that I need to account for?
