I think I see the problem, bootconfig script uses ZFSBOOT_DISKS variable that isn't defined and always empty and auto-detection must be unreliable in some cases, at least for me as I reproduced it on another system with NVMe device adding a SATA disk as well (didn't look into the details).  Should be easy to fix, review incoming.
