package conflict with default packages

[dadez73]

Hi,
i was wondering if didn't make sense to add a check if packages resources are aready declared in other modules or config adding in the install.pp manifest
i tought something like this...
if $samba::package_manage {
if ! defined(Package[ $samba::packages[server]]) {
package { $samba::packages[server]:
ensure => $samba::package_ensure,
}
}
if ! defined(Package[$samba::packages[utils]]) {
package { $samba::packages[utils]:
ensure => $samba::package_ensure,
}
}
}
