ZFS prefers one device name to the other just because the path is stored in metadata. If for some reason device with that name is not found during boot, vdev_geom starts looking for alternatives. If pool imported manually, then it is done by zpool tool. After alternative found, the new name is stored in metadata, fixating it forever. I suppose zfsd may do something alike. I don't think any of them have any bias toward paths with gptid. Unfortunately I have no idea how to debug it unless some reproduction scenario is found.

We have 4 customers and 1 internal system now that have shown this problem.
We have drives that are losing their GPTID labels and being re-added into the zpool with their /dev/da#p1 identifiers.
I, unfortunately, only have debugs from 2 customers systems because I brushed off the other 3 occurrences as "flukes". We're up to 5 instances now which means we more than likely have an issue.
