Hi Trond,

Mind you, this is a Live CD env.  I am doing zpool mirror on a system =
during install.

At any rate, in 9.2 beta 1 it shows;

NAME   PROPERTY    VALUE       SOURCE
zroot  mountpoint  /mnt/zroot  default

On 9.1 it shows;

NAME   PROPERTY    VALUE       SOURCE
zroot  mountpoint  /mnt  local

HTH and hope I am doing something wrong.
