I am currently using OpenSolaris 2009.06
If I was to upgrade to the current "developer" version, forgive my ignorance
(since I am new to *solaris), but how would I do this?
Also, are there docs for this yet on what has changed? I am looking in the
directory there, and I don't see any "notes". Any gentle nudge in the
right direction would be appreciated :)

If I was to take this route, I was under the impression that ZFS takes the
drive as a whole, regardless of partitions, and wipes the data? Apparently
I am wrong?
I don't have any problems with losing a few gig if needed, to save future
problems. If I have to partition a drive of 2tb to 1.8tb (2 trillion bytes
= 1.862g), then oh well.
