Not happy with having to install the port but that worked.
I removed openzfs and openzfs-kmod via pkg remove.
Then  did a 'make install clean' from sysutils/openzfs (2020081800) with r3=
64030 BE
active.
Once I confirmed the port installed a newer /boot/modules/openzfs.ko I
destroyed r364030-OpenZFS and created it again so it would be in sync
with r364030 and it would have the latest openzfs.ko.

When I imported my backup pool (single drive, 1 vdev)
/etc/zfs/zpool.cache was automatically created.

So now I have 2 zpool cache files

 [~] ls -l /boot/zfs/zpool.cache /etc/zfs/zpool.cache
 -rw-r--r--  1 root  wheel  1456 Aug 22 22:04 /boot/zfs/zpool.cache
 -rw-r--r--  1 root  wheel  3088 Aug 22 22:54 /etc/zfs/zpool.cache

 [~] zpool get cachefile zroot backup
NAME    PROPERTY   VALUE      SOURCE
backup  cachefile  -          default
zroot   cachefile  -          default

So the port does work even with running the GENERIC-NODEBUG kernel.

Is it even possible to build a port only into a new BE and not the
current one given how /usr is not mounted?
Now I had to polute the active BE which could get me into trouble.
I was hoping using BEs I could experiment by installing a port straight int=
o the mounted BE.
If that is possible I wouldn't mind getting some pointers on how to make th=
at work.
