(1) the error message you're seeing is because "log-crucial-data" does  
not exist in the PATH under which this script runs. you should either  
explicitly set the PATH variable at the top of your "run" script, or  
(this is how i would do it) explicitly specify the full path to the  
"log-crucial-data" program.

(2) you need to study your shell scripting a little more...  
specifically, learn what "exec" means.

(3) as paul has already pointed out, your directory structure is  
wrong. each directory "/service/x" represents one service. each  
service directory has a "/service/x/log", which receives the logs from  
the service running in its parent directory. my own server has a  
directory structure like this:

/var/service/dnscache/
/var/service/dnscache/run
	(created by dnscache-conf, not changed)
/var/service/dnscache/log/
/var/service/dnscache/log/run
	#!/bin/sh
	exec setuidgid dnslog multilog t ./main
/var/service/dnscache/log/main/ (owned by userid "dnslog")

and then "/service/dnscache" is a symlink to "/var/service/dnscache".


so probably what you want is:

/var/service/clockspeed/ (root:root 0755)
/var/service/clockspeed/run (root:root 0744)
	#!/bin/sh
	echo starting
	exec /usr/bin/clockspeed 2>&1
/var/service/clockspeed/log/ (root:root 0755)
/var/service/clockspeed/log/run (root:root 0744)
	#!/bin/sh
	exec setuidgid cruxlog multilog t ./main
/var/service/clockspeed/log/main/ (owned by userid "cruxlog", 0700)

(i'm not sure how your "log-crucial-data" program is supposed to fit  
in here, you haven't told us what it does or how it works.)

that's a big part of it. if you're going to manage servers, you pretty  
much have to know scripting- shell scripting is a basic requirement,  
and perl can make your life a lot easier as well (although it's not  
"as" required as shell scripting is.)
