[launchd-dev] Diagnosing launchd daemon failure to launch

Hello all,

	I was wondering if you could help me with a launchd issue I'm having  
problems with. I've built my daemon and installed it in /Library/ 
PrivilegedHelperTools. I've made a launchd plist for it, and put the  
plist in /Library/LaunchDaemons.

	Then I reboot, and run 'launchctl list' in the terminal. I can't see  
my daemon; it appears that it didn't get loaded. If I then run  
'launchctl load /Library/LaunchDaemons' and then run the 'list' again,  
I can see the daemon with a pid. This tells me that the plist and the  
file locations are okay, I think.

	I don't see anything in the console logs (I previously had problems  
with the ownership of the plist, but that seems to be fixed).

	Would anyone have any idea what's going wrong, or how I can diagnose  
the problem?

Thanks in advance,

Iain Delaney
