'service named reload' with non-default system directories.

[Ian FREISLICH]

Hi

I often run named outside of the system default directories so that
amongst other things a mergemaster fumble doesn't break my name
servers.  This however breaks rndc because it is not imbued with
the clue of where to find its key.

/etc/rc.d/named does create the key file in the correct place
according to the configured chroot directory.  The reload section
just doesn't tell rndc where to find it.

Can I suggest for a minimal change:

--- /usr/src/etc/rc.d/named     2013-04-15 20:17:58.000000000 +0200

 {
-       ${command%/named}/rndc reload

 }

A more invasive change:

The bind9 reference suggests that named loading rndc.key is for
backwards compatibility.

   "Since the rndc.key feature is only intended to allow the
   backward-compatible usage of BIND 8 configuration files, this
   feature does not have a high degree of configurability. You
   cannot easily change the key name or the size of the secret, so
   you should make a rndc.conf with your own key if you wish to
   change those things.

So, I 'include "path/to/rndc.key";' in named.conf, add a controls
section that uses this named key and I use the following rndc.conf:

---named.conf---
include "/etc/namedb/rndc.key";

controls {
        inet 127.0.0.1 allow { 127.0.0.1; } keys { "rndc-key"; };
};
---named.conf---

---rndc.conf---
include "/etc/namedb/rndc.key";

options {
        default-server  localhost;
        default-key     rndc-key;
};

server localhost {
        key     rndc-key;
};
---rndc.conf---

And the following version of the above patch:

--- /usr/src/etc/rc.d/named     2013-04-15 20:17:58.000000000 +0200
+++ /etc/rc.d/named     2013-04-24 16:16:52.000000000 +0200

this will allow the rc system to reload and stop named (without a
kill) no matter what the configured chroot is.
