should zfs care so much about device name changes

[Nikolay Denev]

Hello,

I wanted to test the new option ATA_CAM, but that would require a boot from another media (USB Drive/CD) and a zpool export/import
to update the vdev names. (actually it's shown as "path" in the zpool.cache file) because otherwise the system would refuse to open/mount
the pool.
But is that really necessary given the fact that all the devices are here, and have matching GUIDS to those in the zpool.cache file?
Shouldnt ZFS just import the pool? 

In the current state what would one have to do to for example test ATA_CAM on a remote machine, where export/import from a rescue
media is not possible?

Thanks,
Niki
