Feature Request: Let zsys manage a newly migrated user dataset that replaced the default installed dataset

[odror]

Describe the bug
When migrating user dataset from an old system to the new one. It is not updated by zsys.

To Reproduce

use zfs send/receive to move the dataset. Then rename mount directory or remove the current dataset so that it will not conflict. verify that the mount directory in the received dataset is correct.

zsysctl save - v

should generate zsys snapshot. It does not.

I get the following error.

INFO Requesting to save state for user "dror"
INFO Couldn't find any association for user dataset rpool/USERDATA/dror_zo0whd

Expected behavior
a zsys snapshot should be generated.

I found a workaround for the issue.
I had to change the dateset property property com.ubuntu.zsys:bootfs-datasets to match the new computer.

Please include a command to include new user datasets.

This is not a workaround, but the actual implementation :)

I would rephrase the bug to something like a feature request: "Please include a command to include new user datasets" (this would ensure the dataset is set in /USERDATA/ + proceed the same tagging as you did). Mind retitling it?
