Like this?

     temporary

         By default, all pools are persistent and  are  automati-
         cally  opened  when the system is rebooted. Setting this
         boolean property to "on" causes the pool to  exist  only
         while  the  system is up. If the system is rebooted, the
         pool has to be manually imported  by  using  the  "zpool
         import"  command.  Setting this property is often useful
         when using pools on removable media, where  the  devices
         may  not  be  present when the system reboots. This pro-
         perty can also be referred to by  its  shortened  column
         name,  "temp".

Interesting... it is in b76.  I checked several other releases both
before and after and they didn''t have it either.  Perhaps it is not
part of the committed interface.  I stumbled upon it because I thought
that I remembered "zpool import -R / poolname" having the behavior you
were looking for.  The rather consistent documentation for "zpool
import -R" mentioned the temporary attribute.

We actually changed this to make it more robust. Now the property is 
called ''cachefile'' and you can set it to
''none'' if you want it to behave
like the older ''temporary'' property.
