hehe... no, that wasn't it.  Being OP, I can say that when I first
booted from livecd... I ran zpool import but saw something called
xpool.

I think I may have meddled around a bit before running that.   Can't
recall for sure now, but it seems mighty suspicious that the
information I was working from on my first attempt mentions xpool in
it.

I'd say its a good bet I blundered around with zpool and managed to
rename rpool to xpool in a frenzy of ill-informed flailing.

Also the instructions I was working from was not about recuing rpool
but other zpools so I imagine the author use xpool as a generic name.

I did not exercise the normal cautions since the OS being rescued was
a newly installed vbox oi that I had not done much with yet so no
great loss was threatened.

If I emerge from this experiment with enough info to do a
rescue... I'm a happy camper, even if I did go ahead and just
reinstall from livecd rather than keep mucking around, I think I could
do a rescue now if need be.
