with difficulty i suspect. You will probably have to specify an alternate
root and zpool.cache file. Then copy the cache file onto the zpool before
powering down, and NOT exporting.
If you don't use an alternate zpool.cache file I suspect you will get issues
as the test systems zpools will be referenced in there, and will cause a
pickle when you bring the broken system up.
Its probably best to use a non zfs based rescue system just to keep things
