Puppet users - Feb 2013 - Puppet 3.1 - remove packages in order/with dependancies.

Hi All.

I would like to remove packages in a specified order because they are 
connected with dependencies.
I use:
#cat /etc/redhat-release;uname -r
CentOS release 6.3 (Final)
2.6.32-279.9.1.el6.centos.plus.x86_64
#rpm -qa | grep -i puppet
puppet-3.1.0-1.el6.noarch

In my module manifest:
class base::dell {
..
        package { "Lib_Utils": ensure => absent }
        package { "MegaCli": ensure => absent }
..
}
Is there a way to ensure that MegaCli will be uninstalled before Lib_Utils 
and then Lib_Utils will be removed? How can I in puppet language enforce 
package dependencies in this case?

Best regards,
Rafal Radecki.

Hi Rafal,

the before meta-parameter would help you here:

package{ ''Lib_Utils'':
  ensure => absent,
  before  => Package[''MegaCli''],
}

Cheers

Or you could turn it around and use "require =>
Package[''Lib_Utils'']"
metaparameter on Package[''MegaCli''].  For inter-packages
dependencies on a
system with a decent package manager (such as CentOS with yum/rpm), 
however, I would urge you to make sure your packages declare their 
dependencies correctly, and then just let the package manager handle it.
