[scourge]

is this a joke? - "my entire production..." you're a devops engineer? - "link where one can read about the rational.." with good grammar? - "why systemd was needed... " ok you lost me there - "the person who started off the initial project?" and you've been hidden under a rock for the past 10 years??

are you seriously trying to tell me that someone is going to have to explain what a "container" is by comparing with chroots? :D how have you been running your production stack all these years if you didn't have an internet connection under your rock :)
