Justin,

Thanks for pointing that out - it was a typo (cut & paste fatigue).  
The corrected versions are attached below.

I haven't run a registry peer and a bridge on the same machine so  
hadn't noticed that. I believe it can be addressed as follows.

In Red Hat, Fedora etc., systems, the boot scripts are run in  
alphabetical order, so "agbs" would normally run before "agregistry".  
To regulate this more precisely, the chkconfig command adds numbers  
to the beginning of the script names when it installs them e.g. a  
bare "agbs" is converted to S85agbs. The added numbering is specified  
in the script itself and both agbs & agregistry _were_ set to the  
same by the line
	# chkconfig: - 85 15
so the added numbering had no effect on the startup ordering.

I've changed those lines in the agbs & agregistry scripts so that  
agregistry will become S86agregistry and will therefore start after  
the bridge server (which remains at S85agbs). I also changed the  
venue server so that it will become S84agvs after chkconfig.

To summarise the installation:
	put the *.conf files into /etc/default/
	put the bare scripts into /etc/init.d/
	run 'chkconfig --add' for each service to be enabled
	run 'chkconfig <servicename> on' for each service to be enabled e.g.  
'chkconfig agbs on'

Of course, you can edit the scripts so that chkconfig will assign  
different prefixes (and therefore startup ordering) to the script names.


Please anyone, feel free to correct anything here - I'm not a Red  
Hat, Fedora etc. person, so my understanding may be somewhat simplistic.
