Is there a way to specify in a launchd.plist that it depends on a kext
first being loaded during system boot?

I have a daemon that should be launched by launchd only after the
network drivers (e.g. com.apple.iokit.AppleYukon on a MacBook Pro)
have been loaded.


As far as I know this can't be done through the launchd plist.

When my daemon starts I check to see if the kext is running. If it's not running I use IONotificationPortGetRunLoopSource to get notified when it *does* start, and I do the KEXT related initialization then. Look at the IOKitLib documentation for this function and IOMasterPort/IOServiceMatching/IOServiceGetMatchingService etc.
