Hacked acl puppet module for adding acl to the main partition of a precise64 vagrant box. This manifest is quite dangerous because you could break your complete box when used in the wrong way.

acl.pp

class acl(
  $needle = '/precise64-root',
) {

  package { "acl":
    ensure => installed,
  }

  # https://gist.github.com/4595997
  exec { "add_fstab_acl":
    command => "/bin/sed -i.backup '/${needle}/s/errors/acl,errors/g' /etc/fstab",
    unless => "/bin/grep -E '${needle}.*acl,errors' /etc/fstab",
    path => "/usr/local/bin/:/bin/",
  }

  exec { "remount-root-partition":
    command => "mount -o remount /",
    path  => "/bin",
    unless  => "mount | grep acl 2>/dev/null",
    require => Exec["add_fstab_acl"],
  }

}
