I literally built a NAS this past weekend and put TrueNAS on it and man has it been humbling learning to administer it. I’m able to get basic stuff working now after drowning in permissions hell for a day but I’m basically getting myself out of that by doing the linux equivalent of running more and more things as administrator in Windows until I stop getting errors. I might well have been a Synology customer before they did this nonsense but now I’m going to end up learning how to run a Linux server at least semi competently.
