Hello

There is a problem with dns/nsd startup script. 
This script reads pidfile location from configfile.
However if NSD is started in chrooted environemnent
then startup script can't locate pidfile and stop the daemon.

I tried to configure pidfile location to /var/run/nsd in nsd.conf
and then created this directory under relative path to chroot directory 
but it didn't help as  nsd-checkconf checks whether pidfile is 
relative to chroot or no:

[root at ns348344 ~]# /usr/local/sbin/nsd-checkconf -o pidfile
/usr/local/etc/nsd/nsd.conf
/usr/local/etc/nsd/nsd.conf: pidfile /var/run/nsd/nsd.pid is not relative to
chroot /usr/local/etc/nsd/.
/usr/local/etc/nsd/nsd.conf: 1 semantic errors in 1 zones, 1 keys.
[root at ns348344 ~]#

The best would be read to variable from config if chroot is in use  by issuing
/usr/local/sbin/nsd-checkconf -o chroot /usr/local/etc/nsd/nsd.conf
and then concatenate this path to pidfile location to get the real path.


Also I found out that removing pidfile variable from startup script solves the
problem and pidfiles are automatically discovered. It seems that /etc/rc.subr
does some magic over that.
