Hmm, interesting. What is your use case for this? The built-in feature detection of NFD is basically Linux-only and relies heavily on e.g. Linux sysfs and standard filesystem hierarchy. OTOH, nfd could be used as a general labeling solution: disable all built-in (Linux-specific) feature detection and run your own hooks or sidecars doing the detection 🧐

Out of curiosity, I quickly created a patch that should allow darwin builds: #808

Please try out and report back. I think we could merge that if it is useful to you even if we don't officially support anything else than Linux (yet).

It would be great to have it at-least compile on Mac, even if the service is going to be deployed on Linux. Yes thanks, it worked, will be useful for getting it to compile.

Yeah, sure. Let's get #808 merged (you can comment +1 it)
