Description of problem:
In default configuration, when resolv.conf is empty, getaddrinfo() returns EAI_NONAME instead of EAI_AGAIN (as it used to in F9).

This makes ntpd useless when NetworkManager is enabled, because ntpd won't try to resolve the name later when NM has setup resolv.conf.


Version-Release number of selected component (if applicable):
glibc-2.8.90-11

How reproducible:
Always

Steps to Reproduce:
1. > /etc/resolv.conf
2. gcc -x c - <<EOF
#include <sys/types.h>
#include <sys/socket.h>
#include <netdb.h>
#include <string.h>
#include <stdio.h>

int main() {
	struct addrinfo hints, *addr;

	memset(&hints, 0, sizeof(hints));
	hints.ai_family = AF_UNSPEC;

	printf("%d\n", getaddrinfo("0.fedora.pool.ntp.org", NULL, &hints, &addr));
	return 0;
}
EOF
3. ./a.out
  
Actual results:
-2

Expected results:
-3
