Use o fantoche para definir o nome do host?

Question

Existe alguma maneira de definir o nome do host de um servidor usando o fantoche?

Eu poderia escrever um tipo personalizado, mas talvez haja uma maneira mais simples.

Obrigado

[Editar] Desculpe, eu deveria ter mencionado que eu corro fantoche de marionete, marionete é configuração primeiro e depois configura todo o resto.

Veja a minha definição de "renomear" para ideias. Ele assume o Debian e pode funcionar no Ubuntu também.

define rename() {
    # We only need puppet so we can restart it. In practice, there's
    # little point in renaming a machine through puppet without a
    # running puppet service
    include puppet::conf

    # We only need apt because puppet management of its package
    include apt

    host { "$hostname": ensure => absent }

    host { "$fqdn": ensure => absent }

    $alias = regsubst($name, '^([^.]*).*$', '')

    host { "$name":
        ensure => present,
        ip     => $ipaddress,
        alias  => $alias ? {
            "$hostname" => undef,
            default     => $alias
        },
        before => Exec['hostname.sh'],
    }

    file { '/etc/mailname':
        ensure  => present,
        owner   => 'root',
        group   => 'root',
        mode    => 644,
        content => "${name}\n",
    }

    file { '/etc/hostname':
        ensure  => present,
        owner   => 'root',
        group   => 'root',
        mode    => 644,
        content => "${name}\n",
        notify  => Exec['hostname.sh'],
    }

    exec { 'hostname.sh':
        command     => '/etc/init.d/hostname.sh start',
        refreshonly => true,
        notify      => Service['puppet'],
    }
} 

define rename::domain() {
    rename { "${hostname}.${name}": }

    common::line { 'remove_old_domain':
        ensure => absent,
        file   => '/etc/resolv.conf',
        line   => "domain $domain",
    }

    common::line { 'add_new_domain':
        ensure => present,
        file   => '/etc/resolv.conf',
        line   => "domain $name",
    }
}

Crie um módulo sethostname. Aqui está o init.pp :

class sethostname {
  file { "/etc/hostname":
    ensure  => present,
    owner   => root,
    group   => root,
    mode    => '0644',
    content => "$::fqdn\n",
    notify  => Exec["set-hostname"],
  }
  exec { "set-hostname":
    command => '/bin/hostname -F /etc/hostname',
    unless  => "/usr/bin/test 'hostname' = '/bin/cat /etc/hostname'",
    notify  => Service[$rsyslog::params::service_name],
  }
}
