This sounds messy, not sure if it has any informative value.
I think I've seen something like this after some reason ZFS import from upsteam
when my kernel and userland were out of sync.
Do you do a full boot from the livecd?  Or do you boot your kernel but then mount
userland from the cd?
In any case, not sure if this is relevan to your main trouble.

bootfs property should not better.  Multi-pool configurations has been tested
before the commit.
