resolver ... again

Howdy,

The code in inet_config.erl is not quite right.
On linux, the code in the inet_config:init/0
reads /etc/hosts.conf (only)

The glibc resolver reads both the /etc/host.conf aswell
as /etc/nsswitch.conf

A very old system

[root <at> rall /root]# cat /etc/redhat-release 
Red Hat Linux release 6.2 (Zoot)
[root <at> rall /root]#  strace ping -c 1 www.erlang.org 2>&1 | grep '/etc/.*.conf'
open("/etc/resolv.conf", O_RDONLY)      = 4
open("/etc/nsswitch.conf", O_RDONLY)    = 4
read(4, "#\n# /etc/nsswitch.conf\n#\n# An ex"..., 4096) = 1767
open("/etc/host.conf", O_RDONLY)        = 4

Slightly newer ....

# cat /etc/redhat-release
Red Hat Linux release 7.3 (Valhalla)
# strace ping -c 1 www.erlang.org 2>&1 | grep '/etc/.*.conf'
open("/etc/resolv.conf", O_RDONLY)      = 3
open("/etc/nsswitch.conf", O_RDONLY)    = 3
read(3, "#\n# /etc/nsswitch.conf\n#\n# An ex"..., 4096) = 1682
open("/etc/host.conf", O_RDONLY)        = 3
