What's weird and funny is the collapse in complexity this represents. Linux, NT, BSD, and other modern kernels implement all kinds of complexity around user/group management, ACLs, security policies, file types and permissions, and so on. If we're moving to unikernels and containers and similar, all that has been replaced with stupid simple access control systems like API access tokens or login/password pairs for cloud service control panels. Your AWS access token is now a single security credential for your entire infrastructure. Of course I'm sure the cycle of reincarnation will continue. Things like Docker or the AWS API will grow in complexity until they at least subsume the entire feature set of Unix UID/groups, Unix/NT ACLs, SELinux, etc.
