>Description:
	named(8) has changed the default location of its pid file,
	from /var/run/named.pid to /var/run/named/named.pid.

	/etc/rc.d/named does not know this.

        Due to chroot usage, the pid file is actually created
        in /var/chroot/named/var/run/named/named.pid,
        whereas the outer /var/run/named is a symlink to
        /var/chroot/named/var/run/named.pid.  This causes "/etc/rc.d/named
	stop" to be unable to stop the named process.

>How-To-Repeat:
	Code inspection
>Fix:
	One or more of the following:

	* Change the built-in default back to /var/run/named.pid.

	* Leave the built-in default as the incompatible new
	  value /var/run/named/named.pid, but provide

		options { pid-file "/var/run/named.pid"; }

	  in the default and sample named.conf files.

	* Adjust /etc/rc.d/named.conf to create the symlink as

	  /var/run/named.pid -> /var/chroot/named/var/run/named/named.pid

        * Document the change in src/doc/CHANGES and in release notes
          for the next version of NetBSD.

 The reason they changed this is:

 2486.   [func]          The default locations for named.pid and lwresd.pid
                         are now /var/run/named/named.pid and
                         /var/run/lwresd/lwresd.pid respectively.

                         This allows the owner of the containing directory
                         to be set, for "named -u" support, and allows there
                         to be a permanent symbolic link in the path, for
                         "named -t" support.  [RT #18306]

 Note that on NetBSD the PID files should _never_ be writable by anyone
 other than root.  The /etc/rc.d infrastructure trusts their content.

 Named should be fixed (once again) to create its PID file before
 changing its runtime user-ID and/or doing chroot.

State-Changed-Why:
It has been over a decade since this ticket was opened.
Two days after this ticket, the etc/rc.d/named was changed:
revision 1.19
date: 2009-04-22 18:27:03 +0000;  author: christos;  state: Exp;  lines: +2 -2;
Adjust for new default location of the pid file.

While this didn't reflect all the discussion in this ticket,
also since then named was changed to use root for the pid file even
when running as non-root.
