Indeed, that's normal. v1 configurations will start the resources on
take-over, and doesn't have enough memory to know it already has them.

As "start" must succeed if already started, no harm should come from
this for correct resource agents.

NOTABUG.

It's only used as authorisation when "autojoin" is enabled. That is the
whole point of the autojoin method.

Users should not run distinct clusters on the same network media. (ie,
the same subnets + port when using bcast, nor the same mcast address +
port.)

When autojoin is not enabled, this will cause a bunch of errors. If they
have distinct shared secrets, they'll bail at the authentication step.

If they have _both_ the same key _and_ the same media _plus_ autojoin
enabled, they'll merge into one big cluster.


Sincerely,
Lars

Ahhh. Ok. I thought you wanted to symlink the entire resource.d
directory out of there ;-)

Of course, special attention needs to be paid to upgrading to (and
possibly, back off from) a version with that change.

There may be files in there which aren't owned by our package though, or
modified.

Looks OK.

Alan, could we get the code review process to be a at-least-two-pairs of
eyes system? It's difficult to handle changes while you're traveling ;-)
