True.  But I was making a brief suggestion to Michelle - who does not seem 
to be a trusting fan of ZFS - hoping that she might actually implement it, 
or something similar.  Or at least an already-tediously-long mailing list 
thread would end.  Rsync is good enough for her situation, and would let 
her use UFS on her off-site backup servers, if she preferred that.
