> Historically Linux implemented DNS control using config files read by the C library. On Linux for not really good reasons the C library is perceived as an optional gateway to the kernel rather than the primary OS interface as it is on other operating systems like macOS or Windows, so statically linked programs or programs that don't use the C library ended up bypassing your configured DNS resolvers. I'm not a systems programmer and haven't touched C/C++ since college. Though I'd like to learn more. Do you have any links that explain how different operating systems rely on standard C libs vs direct system calls for things like DNS? I guess I don't really remember how system calls are made without importing stdlib and other posix libs like pthreads.
