Can't boot on ZFS -- /boot/zfsloader not found

[Jeremie Le Hen]

Hi,

I'm in the process of transferring my home server to an Intel NUC. I've zfs
send/receive'd the whole pool to the new drive and first followed
[ZfsOnGpt] but it fails in the first stage boot loader. The USB keyboard
doesn't seem to be recognized so I can't really debug anything.

Then I tried both [ZfsInMbrSlice]
but it complains that it can't find /boot/zfsloader. Again USB keyboard
doesn't work.

Both times I've been very careful to install the bootcodes at the right
place.

1. Any idea why the USB keyboard doesn't work?
2. Any idea what can be wrong in the setups I tried? How can I debug this?
