I think you've mixed up arguements here. We're discussing the idea of 
porting ZFS to NetBSD, not necessarily using it as a general-purpose file 
system. I think there are a lot of uses of FFS that won't be replaced by 
ZFS. That fact, however, does not mean there aren't uses of FFS that we'd 
rather replace with ZFS. :-)

The problem with Hammer is that it's not ZFS. Some sites will use ZFS and 
some will use Hammer. Having one of them in NetBSD should not preclude 
having the other.

The reason for a port of ZFS would be so that I do not have to run 
something other than NetBSD to get access to it. :-)

Take care,
