I have noticed a bunch of artefacts left over from unclean shutdowns, = which I assume are caused by the above not calling the shutdown rc.d = scripts. Do you know if this is likely to get implemented any time soon, = or are you aware of a simple workaround? I have to say that in general I am finding FreeBSD 12.2 on t4g pretty = good and surprisingly stable. The CPU utilisation is different in terms = of metrics, and I cannot quite put my finger on it, but the web apps = seem to run faster. Of course, it is nice that it is also cheaper.
