ZFS on Debian always uses drive-letter devices instead of ata-, scsi- or wwn- devices

Debian 12.9.
I am trying to find out how I can specify device paths that ZoL keeps and does not just replace with the /dev/sdXn label.

I tried all possibilities that /dev/by-id offers: ata-, scsi-, wwn.
But these never get used by ZoL.
ZoL always replaces them with /dev/sdXn drive letter devices, no matter what I try.

Thus the ZFS pools sometimes only live up to the next system reboot, and then fail because the order of the drive-letter-devices changed.

I used ZFS for years on FreeBSD, never had that issue.

So my question: How do I have to specify the devices so ZFS does not the drive-letterl-devices instead?

zpool export pool_name
zpool import -d /dev/disk/by-id pool_name

However both wwn- and scsi- links exist there, so one might need to specify devices manually:

zpool import -d /dev/disk/by-id/wwn-00000 -d /dev/disk/by-id/wwn-00001 pool_name

-d can be used multiple times, I guess one should remember to enter all disks that the pool uses.

Personally, I tend to use -d when creating the pool.

Filip, thank you very much.
I guess the issue with the drive-letter-pathes was caused by calling zdb -l with /dev/sd... instead of uuid.
This seems to be avoidable by religiously avoiding drive-letter-designations

Your answer led me to another important issue: the problems caused by all options set to "active" if not being explicitly disabled.
See also issue #5142 .
Thus I have opened another discussion on this.

Sorry, I've confused zpool import -d /dev/... with zpool create -d... which I've never used.
🤦🏼

I meant to say that I usually specify desired/prefered dev paths while creating the pool, thus I do not need to do zpool export and then zpool import -d /dev/...
