>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.
