[OpenIndiana-discuss] Where is received filesystem

I've been tinkering with send/receive trying to understand how it all

I've found what appears to my inexperienced eyes to be something of an

I successfully sent/received two filesystems:


I think I made some changes in a certain script, and maybe more than 1
since that move.

So since the amount of data in zp2/hosts is nearly minuscule (5
scripts), I decided to just send/receive zp2/hosts on the old server
to zp2/hosts_old, then at my leisure, investigate the differences.

Inadvertently, I forgot to take off the -R flag and so used this

   zfs send -R zp2/hosts at 111030_14:43:17_0 |
                      ssh zfs recv zp2/hosts_old

And received this warning:
  WARNING: could not send zp2/hosts/reader at 111030_14:43:17_0
  exist cannot mount '/hosts': directory is not empty

I don't understand either part of that warning.  I've already posted
about the first part (reader at 111030_14:43:17_0) so here just
questioning the second part....

Why would `/hosts' need to be mounted? (I think it is about the
receiving host.. right?)

But what is really puzzling, is that newserver reports that data set
to be present:
  zfs list -r zp2

  zp2               10.2G   193G    31K  /zp2
  zp2/hosts         10.2G   193G   464K  /hosts
  zp2/hosts/reader  10.2G   193G  4.29G  /hosts/reader
  zp2/hosts_old      528K   193G   464K  /hosts

So has the content of zp2/hosts been overwritten?
