Browse Source 
Note that this commit brings only formatting changes that were done
during the final review of the illumos change, because FreeBSD got the
main changes before illumos.

  This is an import of the temporary pool names functionality from ZoL:

  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.
