Re: "Anyway, I'm glad the problem is both fixed..."

I want to know HOW it can be fixed?  If they fixed it, this will invalidate 
every pool that has not been changed from the default (Probably almost all of 
them!).  This can't be!  So what WAS done?  In the interest of honesty in 
advertising and enabling people to evaluate their own risks, I think we should 
know how it was fixed.  Something either ingenious or potentially misleading 
must have been done.  I am not suggesting that it was not the best way to 
handle a difficult situation, but I don't see how it can be transparent.  If 
the string "fletcher2" does the same thing, it is not fixed.  If it does 
something different, it is misleading.  

"... and avoidable on the broken systems."

Please tell me how!  Without destroying and recreating my zpool, I can only fix 
the zfs file system blocks, not the underlying zpool blocks.  WITH destroying 
and recreating my zpool, I can only control the checksum on the underlying 
zpool using a version of Solaris that is not yet available.  And then (Pending 
relling's response) may or may not *still* effect the blocks I am concerned 
about.  So how is this avoidable?  It is partially avoidable (so far) IF I have 
the luxury of doing significant rebuilding..  No?
