If anyone else finds the Linux userspace boot debate confusing, try running:

    strace -ff dig icann.org 2>&1 | tee ~/dns.log

I normally don't care that much about DNS. At least not until I notice things like a fresh Linux install having a 1000+ millisecond lag to curl a file. Then maybe try to fix it using the standard textbook technique of editing /etc/resolve.conf and then noticing the system somehow reverts my edit within microseconds.

Those are the sorts of engineering practices that help me learn about all the interesting things our Linux community friends like Systemd are doing to... enrich the domain resolution process.

Take a look. What you find may surprise you.
