From my perspective, he doesn't have a problem at all. I would even dispute that he doesn't know the "how." If his servers are configured via chef, then chef is the how. Going deeper and looking at the OS-specific mechanisms chef uses is necessary for debugging when the behavior doesn't seem to match the documentation, just like if you're doing it by hand, iptables is the how, and the system calls or library calls it makes are what you'd look at if you couldn't understand its behavior from the man page and other docs. In other words, you shouldn't worry if you're forgetting something because you never need to use it. When you need to use it, then you will learn it again and count it as an advantage that you did know it at some point in the past.
