2486. [func] The default locations for named.pid and lwresd.pid

Browse Source 
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]
