Puppet users - Nov 2008 - installing rpms in order

I''m guessing i''ve hit the parallel features of puppet, but
just
checking to see if there is a way to execute the array in element
order?

The rpms i''m installing are dependent on each other

I''m doing -

$ganglia = $architecture ? {
        "i386"  => [ "libconfuse-2.5-3.i386.rpm",
"libganglia-3_1_0-3.1.1-1.i386.rpm",
"ganglia-gmond-3.1.1-1.i386.rpm"
] }

ganglia::rpms { $ganglia : }

define ganglia::rpms () {
        package {"${name}": ensure => present,
                provider => rpm,
                require  => Package["apr"],
                source   => "http://$repo/ganglia/${name}"
        }
}

But it can fail on first puppet poll due to it installing gmond rpm
before libconfuse rpm.

I guess I need to specify each rpm in it''s own package {} and use the
before/require syntax?

Thanks,

Matt

for this use the metaparameters like require and before.

there is no way that puppet guaranties that the array is executed in
that order. puppet builds up a dependency graph and will execute that in
the correct order. however it will never guarantee that something
without any dependencies is executed in a certain order.

exactly.
