Subject: bootscripts bug                                                        
Date: Thu, 14 Mar 2002 00:35:04 +0100                                           

I have found a problem with the bootscripts, and tinkered with them a           
little, but found no satisfying solution so far. I have tried version           
1.7. It's all very weird and I am very confused.                                
                                                                                
Apparently the script finds itself when it is called like the daemon it         
is meant to start. For example, I use /etc/rc.d/init.d/squid to start           
/usr/sbin/squid. The script starts up, looks for squid, finds itself,           
thinks, squid is already running, and aborts. That is very weird because        
I'd think that the -o %PPID parameter to pidof (in getpids() in                 
/etc/rc.d/init.d/functions) would filter out the script from the list of        
returned pids. So I added a "ps ax | grep squid" right after the pidof          
command, and had it print the return of getpids to the screen. It looks         
like this (newlines deliberately added to improve readability, he prints        
everything into one line):                                                      
                                                                                
Starting squid ...
