Since I maintain three ports (security/sguil-server, security/sguil-sensor
and security/sguil-client) that have this problem, I decided to start with
the server port. The current port version is 0.7.0 and the init script
worked fine when I submitted the port a while ago. Here it is:
. /etc/rc.subr
load_rc_config sguild
# set some defaults
sguild_enable=${sguild_enable:-"NO"}
sguild_conf=${sguild_conf:-"/%%PREFIX%%/etc/%%SGUILDIR%%/sguild.conf"}
pid=${pid:-"/var/run/%%SGUILDIR%%/sguild.pid"}
sguild_flags=${sguild_flags:-"-D -P ${pid}"}
sguild_user=${sguild_user:-"sguil"}
name="sguild"
rcvar=sguild_enable
command="%%PREFIX%%/bin/${name}"
command_args="-c ${sguild_conf} ${sguild_flags}"
procname="%%TCLSH%%"
check_process="${procname}"
sguild_user="sguil"
run_rc_command "$1"
The sguild program begins with these lines:
#!/bin/sh
# Run tcl from users PATH \
exec tclsh "$0" "$@"
Now I'm trying to update to version 0.8.0, and I cannot get the init script
to work. It's identical to the 0.7.0 version, and so is the beginning of
the sguild program. Yet when I try to start the program, I get this:
# /usr/local/etc/rc.d/sguild start
/usr/local/etc/rc.d/sguild: WARNING: no shebang line in
/usr/local/bin/tclsh8.5
/usr/local/etc/rc.d/sguild: WARNING: no shebang line in
/usr/local/bin/tclsh8.5
/usr/local/etc/rc.d/sguild: unknown directive '/usr/local/bin/sguild'.
Usage: /usr/local/etc/rc.d/sguild
[fast|force|one|quiet](start|stop|restart|rcvar|status|poll)
When I look at /etc/rc.subr, I take the "unknown directive section to mean
"I'm bailing out, because I have no clue what you want me to do."
I can start the daemon manually, and it works as expected:
# sh /usr/local/bin/sguild -c /usr/local/etc/sguild/sguild.conf -D -P
/var/run/sguild/sguild.pid
2012-12-17 16:42:48 pid(77882) Loading access list:

/usr/local/etc/sguild/sguild.conf -D -P /var/run/sguild/sguild.pid
Both status and stop work fine:
# /usr/local/etc/rc.d/sguild status
sguild is running as pid 77884 77888 77889.
[root@buttercup4 /usr/ports/security/sguil-server]#
/usr/local/etc/rc.d/sguild stop
Stopping sguild.
SGUILD: killing child procs...
SGUILD: Exiting...
# ps -auxw | grep sguild
root 77964 0.0 0.0 9128 1452 0 S+ 4:45PM 0:00.00 grep sguild
This makes no sense to me. What is start failing like this? Did something
change in the rc.subr script recently? I don't see anything in
/usr/ports/CHANGES for rc.subr since 2007. I don't see anything at all
about rc.subr in /usr/ports/UPDATING.
If I add a command_interpreter of /usr/local/bin/tclsh8.5, status and stop
fail, claiming sguild isn't running. (It is.)
This one has me stumped.
