Remove MultiArch / i386 in Ubuntu with Puppet

Here’s a little snippet I use to remove multiarch / i386 support from Ubuntu with Puppet.

if versioncmp( $::lsbdistrelease, "12.04" ) > 0 {
    exec { "remove-architecture i386":
        command => "/usr/bin/dpkg --remove-architecture i386",
        onlyif => "/usr/bin/dpkg --print-foreign-architectures | /bin/grep -q i386",
    }
} else {
    file { "/etc/dpkg/dpkg.cfg.d/multiarch": ensure => absent, }
}
