Hmm, thats an approach, but I though you wished to avoid runtime magic?

We need to be able to replace environment variables in the path to do it
generically.

Your suggestion of multiple paths and find the first one solves the
which-platform question - if we can add environment variables into the
paths. At which point the function becomes

currentpath=Config.etcHostsPath;
while (fp ==NULL && currentpath) {
  char *path = substenvvariables(currentpath->data);
  fp = fopen(path, "r");
  safe_free (path);
  currentpath=currentpath->next;
}
