So, I'm wondering if y'all have seen the same thing?It is configurable. See resolv.conf(5), specifically the "rotate" option.
Yes, I'm aware of that, thanks. I'm not wondering what my options are, I'm wondering what behavior people have observed.

I think you'll find that most people on this list are familiar with the challenges you described.
