Crap, now you got me going as to what is happening.  The script is too damn
simple not to work.

Doesn't make any sense.  As a refresher, here is the script:

:
STATE=$1
RUNLEVEL=${RUNLEVEL:-`who -r | awk '{print $3}'`}

case ${STATE} in

'start')
        /usr/bin/fapdbstart
        ;;
'stop')
        /usr/bin/fapdbstop -q
        ;;
esac


Here is a new version of the script:

#!/bin/bash

RUNLEVEL=${RUNLEVEL:-`runlevel | cut -d " " -f 2`}

case "$1" in

    start)
        echo /usr/bin/fapdbstart
        ;;
    stop)
        echo /usr/bin/fapdbstop -q
        ;;
    *)
        echo "Usage: fapsrv {start|stop}"
	;;
esac


First off, it fixes the RUNLEVEL problem.  Secondly it catches a missing
command line option.

Did it make a difference in the operation?  Nope.  Manually running your
script resulted in:

mrvideo.ZROOT <154> ./doit start ; ./doit stop ; doit
who: invalid option -- r
Try `who --help' for more information.
./doit: /usr/bin/fapdbstart: No such file or directory
who: invalid option -- r
Try `who --help' for more information.
./doit: /usr/bin/fapdbstop: No such file or directory
who: invalid option -- r
Try `who --help' for more information.

Does exactly as expected.

I run my version and get:

mrvideo.ZROOT <152> ./doit start ; ./doit stop ; doit
/usr/bin/fapdbstart
/usr/bin/fapdbstop -q
Usage: fapsrv {start|stop}


Of course, if you use what I have, remove the echo from the start and stop
lines :-)

You don't need the ' characters around the case words.

I see no reason why this shouldn't work.

Before the case statement, add the following lines:

date >> /fapsrv.log.out
echo "RUNLEVEL = $RUNLEVEL" >> /fapsrv.log.out
echo "Command option = $1" >> /fapsrv.log.out
echo "" >> /fapsrv.log.out

Change the case line to:

	case "$1" in

and remove the SATE line.  It isn't necessary.

I don't know where you were placing some test lines, but add these and
report back.  I can't create a dummy init.d script and test it, since my
Linux box is my very popular web/ftp server.  Bouncing it up and down
will cause all kinds of grief with users.

Report back what the new log has to say.

Oh, if you want to do some higher level debugging, copy your current fapsrv
script to fapsrv.debug.  Create a new fapsrv script that contains the following:

#!/bin/bash

echo >> /fapsrv.log.out
echo "##########
echo "# Start of $1 run..." >> /fapsrv.log.out
echo "##########

bash -x /etc/init.d/fapsrv.debug $1 >> /fapsrv.log.out

echo >> /fapsrv.log.out
echo "##########
echo "# End of $1 run" >> /fapsrv.log.out
echo "##########
echo >> /fapsrv.log.out
echo >> /fapsrv.log.out
echo >> /fapsrv.log.out


That will give you a line-by-line capture of what the script is doing.

We'll get it yet.
