> Add docs for target machine requirements/expectations
> -----------------------------------------------------
>                 Key: BROOKLYN-477
>                 URL:
>             Project: Brooklyn
>          Issue Type: Improvement
>            Reporter: Aled Sage
>            Priority: Minor
> We should improve our docs for the machine requirements/expectations, for blueprints
to behave as expected.
> This became evident when investigating
(extra stdout when ssh'ing). For example, our docs could say:
> {noformat}
> It is strongly recommended that VMs are configured so that no additional stdout is written

> when executing remote ssh (or WinRM) commands. Such stdout risks interfering with the
> response parsing in some blueprints.
> For example, if configuring the VM to write out "Last login" information, this should
> done for only "interactive" shells (see for
> details).
> {noformat}
> There are no doubt many other things we could mention, such as:
> * {{/tmp/}} should be writable
> * Sufficient entropy (e.g. see
for setting up Brooklyn itself)
> * Outbound network connectivity (but not all blueprints require that)
