On some configurations, zfs-import-bpool.service fails

[alb-i]

The command
zpool import -N[...]
in the zfs-import-bpool.service script fails, indicating that the pool is not found. This can be fixed by adding the boot pool partition device as parameter to the import command.

If anyone stumbles across this issue, I would love to know more about your setup, so we can try to figure out what is causing this.

I have stumbled across this issue, with the exact same symptoms and exact same fix. I followed these instructions basically to the letter: https://openzfs.github.io/openzfs-docs/Getting%20Started/Debian/Debian%20Bullseye%20Root%20on%20ZFS.html , so it was installed as debian bullseye with linux 5.10.0-18-amd64 (5.10.140-1) and zfs 2.0.3-9. The issue also persisted with linux 5.18.16-1 and zfs 2.1.5-1 from bullseye-backports.
The boot and root pools are both on a single samsung nvme and the hardware is a new amd ryzen desktop.

I also noticed that by the time I had a bash prompt, the pool was detected normally and could be imported with a simple 'zpool import -a'.
Please let me know if you want any more info.
