@anemone @Tony @verita84 I ran into crippling bugs that prevented essential features from working, which killed my machine. example: cpu quotas. you can cap a process/systemd service to a fixed number of cores, to a percentage of cpu per core. In Ubuntu is absolutely did not work with containers despite this being a first class advertised container feature. I was having hardware issues at the time and could only keep the server up by rationing resources, which didn't work in containers, so I had to move everything out of the containers.

supposedly all those bugs are fixed now but I don't trust containers anymore.
