There's been a similar problem with graid, are you sure that's
not what's going on here? That the OS has picked up on some

Does this need to be diddled in the running kernel before creating
the zpool/datasets? or is it simply enough to drop it into loader.conf
for the reboot?

I'll run some tests.
