>Description:
If in a random way to commit an error in /var/named/etc/namedb/named.conf,
at which 'named' doesn't start, or to commit an error
in named_wait_host="local" (/etc/rc.conf),
then /etc/rc.d/named will work infinitely, if named_wait="YES".
The computer never to boot.
To avoid such situation, I offer a patch.
>How-To-Repeat:
cat /etc/rc.conf
..
named_enable="YES"
..
named_wait="YES"
named_wait_host="local"
..
# /etc/rc.d/named start
Starting named.
Waiting for nameserver to resolve local
Waiting for nameserver to resolve local
Waiting for nameserver to resolve local
Waiting for nameserver to resolve local
