Log: 9630 add lzc_rename and lzc_destroy to libzfs_core illumos/illumos-gate@049ba636fa37a2892809192fc671bff9158a01cd https://github.com/illumos/illumos-gate/commit/049ba636fa37a2892809192fc671bff9158a01cd https://www.illumos.org/issues/9630 Rename and destroy are very useful operations that deserve to be in libzfs_core. And they are not hard to implement too.
