A couple of things:

* Sorry, my suggestion to use $TEST_VAR_DIR was bogus.  It works with
  local daemons (so helps in autobuild) but doesn't work when you run
  the tests on a cluster because $TEST_VAR_DIR doesn't exist on the
  cluster nodes.

  This patch:

    ctdb:tests: use TEST_VAR_DIR instead of /tmp in integration.bash

  can be dropped for now because the functionality is only used in
  "complex" tests, which need a cluster to run on.  So, we don't need
  this for autobuild.

  The real fix is probably to create and ship 99.test (like 99.timeout
  - probably replacing it).  I have a good idea of how to make it
  work... and get rid of a lot of bogus code in integration.bash.  I
  wrote that code but now I see a much better way.  :-)

  That said, can we please defer the following fix (and, therefore, the
  whole patchset) for a few days?

    ctdb:tests: use TEST_VAR_DIR instead of /tmp in 76_ctdb_pdb_recovery.sh

  For the statd-callout rewrite we added a "ctdb ptrans" command that
  reads data from stdin.  This solves the remote temporary file problem
  by completely avoiding it.  Amitay is going to push those patches
  very soon and then we could fix this properly by using "ctdb ptrans".

* Again, it was my suggestion to 2>/dev/null the output of the cat
  commands in the ip stub.  However, in retrospect, we can just get rid
  of them and replace them with "echo".  Then we shouldn't have a
  broken pipe issue.  I've done this but haven't had time to push this
  anywhere. Wanted to get a reply to you as quickly as possible...

Apart from that we could push most of the patchset, except the bit that
actually makes it get run in autotest.  Let's ping-pong some
more...  :-)

peace & happiness,
martin
