Show HN: A “living” Linux process with no memory

Useful yes, complete no.

Uninterruptible sleep, signals, memory mappings etc have not changed fundamentally.

Namespaces and cgroups are new concepts in Linux, they won't be covered. IIRC user namespaces appeared in 3.14. New cgroup hierarchy got somehow usable much later than that.

The new concepts are needed for containers. Not at all relevant for the original article here.

Actually he is still maintaining a list of changes since the book has come out. http://man7.org/tlpi/api_changes/index.html
