You can define these in /boot/loader.conf:

Maybe that helps.

Those settings control waiting before mounting root.  Harry's problem
is that root is mounted quickly, before other drives are ready for zfs.

The zpool script waits for 'disks'.  It would be nice if the cam
subsystem had something like a sysctl it set to indicate when initial
probing for disks was done, then there could be an rc.d/camprobe script
with 'PROVIDE: disks' which waits for the probing to complete.

kern.cam.boot_delay should still fix it because what is required is a delay

J.

while the devices (all of the disks, zfs or not) get ready. Because root has to happen before disks/zfs. --
