Some details on how the bigbrother daemon script runbb.sh starts

Here is how it gets called. Adding the start argument is *optional*. You
need to send stop signal to stop it


su - bbro /export/home/bbro/bb/runbb.sh $1

# cat runbb.sh
[...]
$BBHOME/bin/bbd >> $BBOUT 2>&1
[...]
{ sleep 30; nohup $BBHOME/bin/bbrun $BBHOME/bin/bb-network.sh ;} >> $BBOUT 2>&1 &
[...]
{ sleep 90; nohup $BBHOME/bin/bbrun -a $BBHOME/bin/bb-display.sh ;} >> $BBOUT 2>&1 &
[...]
{ sleep $EXTSTARTSLEEP; nohup $BBHOME/bin/bbrun -a $BBHOME/ext/$file ;} >> $BBOUT 2>&1 &
[...]
{ nohup $BBHOME/bin/bbrun -a $BBHOME/bin/bb-local.sh ;} >> $BBOUT 2>&1 &

In the above script bbrun is designed to run every 300 secs

Here is where I need help

my bbd run script is

#!/bin/sh
exec 2>&1
exec setuidgid bbro /export/home/bbro/bb/runbb.sh

and my bbd log run script is

#!/bin/sh
exec multilog t /var/log/bbd

I noticed it is keep calling the runbb.sh script. Here is what the log
says

tail -f /var/log/bbd/current

@4000000040da7c0017658e2c Starting the Big Brother System & Network monitor
@4000000040da7c0035a085f4 Big Brother is already running, aborting start procedure
@4000000040da7c032d33192c Starting the Big Brother System & Network monitor
@4000000040da7c0422d6b95c Big Brother is already running, aborting start procedure
[..repeating..]

svstat /service/bbd shows running 1-4 secs then 0 and the 1-4 secs again
svstat /service/bbd/log shows running fine with secs adding gradually

Basically I do not want more that one runbb.sh to run and start it if
someone just kill the process using kill -9 or similar signal. I want it
to not start another runbb.sh if one is running already. Also when I svc
-d /service/bbd I want it to kill the runbb.sh and all the processes
called by it

Is it possible through supervised way?

Thanks for all the help

It seems that runbb.sh puts itself in the background.  This means
that, as far as supervise can tell, the service has gone down, and so
supervise tries to restart it.

If there's a way to configure bb to stay in the foreground, do that.
(Otherwise, you'll have to use fghack.)  Ideally, it should run in the
same process that was originally the ./run script, without leaving a
shell or anything in between.  (If runbb.sh ends with "something &",
you could try changing that to "exec something".)  If a shell process
is left there, or if you have to use fghack, then you won't be able to
use svc -d, although you will get automatic restarts when bb really
does go down.

All it will do directly is kill the top-level process.  Hopefully, bb
will react to that by killing all the processes it started before it
exits.
