Does changing a daemon's plist file extension prevent it from being loaded? I particularly want to disable:
/private/etc/mach_init.d/dashboardadvisoryd.plist.disabled, but in general for any daemon.
Does changing its plist extension prevent it from loading?
In the past I moved them to a different folder, but this is more convenient.
launchctl list and sudo launchctl bstree will show you the jobs. You'll need to read up on the mach_init part as well as be aware that launchd gets more and more of the pie as you go from Tiger/Leopard/Snow Leopard/Lion - your in general question is basically "walk me through launched" - The command mdfind dashboardadvisory will search in the areas hidden by default in spotlight as system files.
