Linux containers are a waste of time because you have to reinvnent the wheel for starting and stopping services. And you have to make sure that your containers are resilient for restarts . You have to spend a lot of time making the container too when you could just deploy once on a machine and it will always work.

Also, containers would be super simple and awesome if they supported system so you don't have to reinvent the wheel for starting apps or services. It's just a time sink
