Instead of "restart", use "exec".

What "restart" does is send a "stop" command and then executes "named".
The problem is that it doesn't know what command-line options you gave to
the original named process, so it can't supply them to the new process.
The new process runs with default options, so it looks at the wrong
named.conf file.

The "exec" operation tells the existing named process to call execv() to
restart itself.  It still has a pointer to its original arguments, so it
can pass them on to the new instance.
