These days most disk drivers will probe for devices asynchronously. This means it's possible that when you zfs init script runs all the required block devices may not yet have been discovered. The result is the pool may fail to cleanly import at boot time. This is particularly common when you have a large number of devices. The fix is for the init script to block until udev settles and we are no longer detecting new devices. Once the system has settled the zfs modules can be loaded and the pool with be automatically imported.
