WIP - Discovers pool and vdev but cannot open /dev/disk node
Can’t read from /dev node via current vnode_open method during early boot, even though BSD subsystem available.
Possible that changing vn_openat to be able to root from /dev may work, have not tried.
Considering using IOKit to address vdev devices, at least for the boot pool - may also be a resolution for the issue of changing /dev/ nodes.
