[nsd-users] about nsd config as root-server

[Shuji Yoshida]

Hi,
I tried to verification to use root-server with nsd（4.2.3）.

NSD compiled with below option:
--enable-root-server
--disable-ipv6
--enable-bind8-stats
--enable-zone-stats
--enable-ratelimit
--enable-ratelimit-default-is-off
--with-libevent=no


And configuration for root zone is below:

zone:
    name: "."
    zonefile: "root.zone"
    include-pattern: "master"
    multi-master-check: yes


And "root.zone" file is below:

$TTL 300
.       IN      SOA     x.rot-servers.net.      postmaster.root-servers.net.    (
                                2020112502                      ; Serial
                                3600                            ; Refresh
                                3600                            ; Retry
                                86400                           ; Expire
                                3600                            ; Negative cache TTL
                                )
                                                IN              NS              x.root-servers.net.
x.root-servers.net.             IN              A              XXX.XXX.XXX.XXX


NSD booted but below log outputted to log file:
---
info: zonefile ..zone does not exist
---

And after checking using dig, SERVFAIl was returned.
Is this configuration and zone file is missed?
