[oi-dev] Filesystems that both Unix and Linux can read

[Atiq Rahman]

Hi Stephan,
AFAIR, I created one of the pools using -d option
and still got following,

*cannot import 'rpool': unsupported version or feature*

*This pool uses the following feature(s) not supported by this system:
 com.klarasystems:vdev_zaps_v2*


I am wondering if vdev_zaps_v2 not excluded by -d
Of course, to be sure, I need to recreate the pool and test again.
