[OpenIndiana-discuss] How to let find 'see' .zfs directories

[Harry Putnam]

Probably some obvious thing going on here but I'm not see how find all
'.zfs' directories under a zfs system hierarchy.

Just running something like 

  cd /rmh/   (that is 'p2/rmh' in zpool talk)
  
  find . -type d -name 'snapshot'  
  
No hits whatsoever, when I know there are 4-5 under there.

I wanted to setup some homeboy snapshot destroys on the basis of mving
to all .zfs/snapshot directories and using ls -t, sed, zfs snapshot destroy to
get rid of snaps beyond the most recent 8 in the directory

So is something like 'zfs -H -t snapshot -o name' the only way to
ferret out actual addresses of the snaps?  

I'd sooner use basic oldschool unix tools if possible
