one thing that baffled me was when I set the mountpoint for zfstank/var - and 
it was gone.  ;) 

But seriously, setting up zfs was way easier than my first steps with mdraid + 
fitting a filesystem on it. It is different (just like office 2010 is easiert than 
2003 but people complain because it is different) but a lot easier. I hope it 
stays that way.

One thing that scares me: it is way too easy to throw away everything..

2012-12-30.05:55:17 zfs set mountpoint=legacy zfstank/var

compared with the hours of fiddling when I started using raid this was pretty 
much straight forward - and yes, I know, destroying var was not necessary, but 
at that point I just wanted to try it... as I said, way too easy to throw away 
everything.
