[Linux-HA] Cloned resources starting on forbidden nodes

[Max Hofer]

Never mind, I found the error. I should have used "#uname" instead of "#id" - seems I had
 the bad luck to copy-pasty a bad example from the web-page.

http://www.linux-ha.org/v2/Examples/Advanced#head-6117d43c2bcaa40ddea4ccadd565534f3cdf0983

The 3rd example looks like:

<rsc_location id="dont_run_named" rsc="named_id">
    <rule id="pref_dont_run_named" score="-INFINITY">
        <expression attribute="#id" operation="eq" value="mars"/>
    </rule>
</rsc_location>

Could anyone fix this type and change #id to #uname, thx
