Ubuntu 22.04 Root on zfs - cannot export 'rpool': pool is busy

Hi, I have issue as below at step 5.10. I use Live CD for 22.04.1.

So after reboot I imported rpool by:

zpool import -d /dev/disk/by-id/{rpool-partition}
zpool import -f rpool
exit

I had the same problem over multiple attempts. I suspected it was because there was a lingering ~ubuntu login that was hanging on to rpool. I never got it to work. Boot fails and down in grub command line (actually I think it was initram or similar). I did something similar

zpool import -f rpool
zpool export rpool

Then booting worked.
