Hi,

I had a possibly similar problem (boot wanting to mount ZFS before usb
had finished recognising the hardware), and asked around.=20
The advice I got led to me putting this in /boot/loader.conf:

vfs.root_mount_always_wait=3D1 # give usb time to settle before zfs
kern.cam.boot_delay=3D"30000"  # 30s delay for usb3 spinning rust

ok a long boot time, but now everything's there as expected. My context
is a rasberry pi4b+(8GB) booting from microsd (ufs) with a 1Tb external=20
hard drive attached (which is zfs mounted) running -current r366312 with
a no-debug kernel.
