The hacker community is primarily a male dominated space, therefore it must be hostile and problematic, shitlord!
Perhaps we should start marketing the term "hackette", and include a pen-test ISO image with every Barbie Thumb Drive.
Seems to be the desperate approach in CS-land.
Those Barbie thumb drives already have them. Not my fault you haven't discovered it yet.
Go work for a contractor. Get to know the feds. Then your resume magically moves to the top in usajobs.gov.
So, should any developer know this? That is debatable. I've had very competent developers who had next to no clue about how DNS works. They could do their job just fine with that. Me? Personally, I'm not up to snuff with the finer points of SQL queries and all the joins that exists and when it makes sense to create an index, etc. Could I find out? Most likely, but I haven't had the need to recently.
The problem is, that you are mapping your knowlegde to "what people must know". I used to do that too, and I probably still do often enough. The DNS example above didn't come from nowhere: I had the case, and I was really thinking "how could such a competent person not know this", but then this person could probably enlighten me about dozens of things I don't know well enough.
It all comes down to what you define as "general knowgledge" for a developer should be and that is highly subjective.
TL;DR Hiring people is hard. Especially, technical people.
The bug doesn't happen in that context:

Of course, the situation is not exactly the same in a virtualized environment.

Judy Carne was best... sock it to me, sock it to me, sock it to me, sock it to me...
We need a sampled and mixed Milhouse Nixon on that line.
So, what's your remedy?
