I get why there are people that don’t like how some installers do this, but this trope is really turning into the “but I don’t even own a TV” of OSS commentary.
Just use the Docker image if you don’t like it. Or get their appliance which actually supports ongoing development.
But every single other reply seems to be either “well yeah obviously read the script first” or “how dumb, just use docker,” so like I said, maybe I’m the dumb one.
