Mounting a NFSv3 share on Debian Squeeze fails:

Jan  3 16:48:28 test123 puppet-agent[15638]:
(/Stage[main]/Atmosfair/Nfs::Client::Mount[homes]/Mount[shared /data/homes by test123.atmosfair.net])
Could not evaluate: Execution of '/bin/mount -o _netdev /home' returned 32:
mount.nfs: rpc.statd is not running but is required for remote locking.
#012mount.nfs: Either use '-o nolock' to keep locks local, or start statd.
#012mount.nfs: an incorrect mount option was specified

The according part of my manifest is

if $::role != 'fileserver' {
  class { 'nfs::client':
    nfs_v4 => false,
    nfs_v4_idmap_domain => undef,
  }
}
nfs::client::mount { "homes":
  share  => '/data/homes',
  mount  => '/home',
  ensure => 'mounted',
  server => 'files',
}
