Re: [Linux-cluster] Indenting resources inside a service in rh el 4.8

Probably I was not completely correct in my assumptions.

The indenting configuration should assure that the inner resource is
started after the outer one. Is this true for rh el 4?
Instead, to have the behaviour regarding resource restatrt and not
whole service restart, in rh el 5.x you should write something like

                        <fs ref="extstoragefs" __independent_subtree="1">
ref="myscript"__independent_subtree="1" />
                                <ip ref=""/>
                                <script ref="mydb"/>

But this seems not to work in rh el 4. Is this supposed to work?
