Okay.
Herein lies the problem: I used /bin/sh plus location of jail plus the
command to start and stop. The system does not seem to be able to find the
script. I have not ran /usr/libexec/locate.updatedb yet. That may help, I
don't know.
Hold a sec, let me test.
exec.start = "/bin/sh /etc/rc.d/jail jail_start";
exec.stop = "/bin/sh /etc/rc.d/jail jail_stop";
