>Description:

In a build with MKUNBOUND=yes the /etc/rc.d/unbound script does not properly
work. Unbound is started in a chroot but the pid file path is not properly
adjusted in the script.

>How-To-Repeat:

Install a MKUNBOUND=yes build and configure unbound to run, then query
its status and try to restart it.

 - add "unbound=YES to" /etc/rc.conf
 - /etc/rc.d/unbound start
 - pgrep unbound (note the pid)
 - /etc/rc.d/unbound status (claims it is not running)
 - /etc/rc.d/unbound restart
 - pgrep unbound (note the pid has not changed)

>Fix:
n/a
