I spent an afternoon figuring out a fairly specific problem involving NFS. There were several surprising pitfalls to be aware of, so I preserved my steps as a self-answered question for posterity:

Mount NFS volume on Ubuntu Linux server from macOS client

The question got closed as off-topic because it didn't have a "clear problem statement". But I'm not sure how to make the question better. It seems pretty clear and precise to me.

Can the question be improved so as to be on-topic? Or is it simply unsuitable for StackExchange? (I could move it to my blog.)
