It is intended to assist the creation and management of virtual machines
that have their rootfs on ZFS on hosts that also have their rootfs on
ZFS. These situations cause SPA namespace collisions when the standard
name rpool is used in both cases. The solution is either to give each
guest pool a name unique to the host, which is not always desireable, or
boot a VM environment containing an ISO image to install it, which is
cumbersome.
As a side note, this commit includes the removal of `zpool import -r`,
which previously did nothing.
