 CoreOS allows you to declaratively customize various OS-level items, such as network configuration, user accounts, and systemd units. This document describes the full list of items we can configure. The `coreos-cloudinit` program uses these files as it configures the OS after startup or during runtime.
 Your cloud-config is processed during each boot. Invalid cloud-config won't be processed but will be logged in the journal. You can validate your cloud-config with the [CoreOS validator]({{site.url}}/validate) or by running `coreos-cloudinit -validate`.
 ## Configuration File
-The file used by this system initialization program is called a "cloud-config" file. It is inspired by the [cloud-init][cloud-init] project's [cloud-config][cloud-config] file. which is "the defacto multi-distribution package that handles early initialization of a cloud instance" ([cloud-init docs][cloud-init-docs]). Because the cloud-init project includes tools which aren't used by CoreOS, only the relevant subset of its configuration items will be implemented in our cloud-config file. In addition to those, we added a few CoreOS-specific items, such as etcd configuration, OEM definition, and systemd units.

 cepgo
 =====
 Cepko implements easy-to-use communication with CloudSigma's VMs through a
 virtual serial port without bothering with formatting the messages properly nor
 parsing the output with the specific and sometimes confusing shell tools for
 that purpose.
 Having the server definition accessible by the VM can be useful in various
 ways. For example it is possible to easily determine from within the VM, which
 network interfaces are connected to public and which to private network.
 Another use is to pass some data to initial VM setup scripts, like setting the
 hostname to the VM name or passing ssh public keys through server meta.
 Example usage:
    package main
    import (
            "fmt"
            "github.com/cloudsigma/cepgo"
    )
    func main() {
            c := cepgo.NewCepgo()
            result, err := c.Meta()
            if err != nil {
                    panic(err)
            }
            fmt.Printf("%#v", result)
    }
 Output:
    map[string]interface {}{
        "optimize_for":"custom",
        "ssh_public_key":"ssh-rsa AAA...",
        "description":"[...]",
    }

 # YAML support for the Go language
 Introduction
 ------------
 The yaml package enables Go programs to comfortably encode and decode YAML
 values. It was developed within [Canonical](https://www.canonical.com) as
 part of the [juju](https://juju.ubuntu.com) project, and is based on a
 pure Go port of the well-known [libyaml](http://pyyaml.org/wiki/LibYAML)
 C library to parse and generate YAML data quickly and reliably.
 Compatibility
 -------------
 The yaml package supports most of YAML 1.1 and 1.2, including support for
 anchors, tags, map merging, etc. Multi-document unmarshalling is not yet
 implemented, and base-60 floats from YAML 1.1 are purposefully not
 supported since they're a poor design and are gone in YAML 1.2.
 Installation and usage
 ----------------------
 The import path for the package is *gopkg.in/yaml.v1*.
 To install it, run:
    go get gopkg.in/yaml.v1
 API documentation
 -----------------
 If opened in a browser, the import path itself leads to the API documentation:
  * [https://gopkg.in/yaml.v1](https://gopkg.in/yaml.v1)
 API stability
 -------------
 The package API for yaml v1 will remain stable as described in [gopkg.in](https://gopkg.in).
 License
 -------
 The yaml package is licensed under the LGPL with an exception that allows it to be linked statically. Please see the LICENSE file for details.
 Example
 -------
 ```Go
 package main
 import (
        "fmt"
        "log"
        "gopkg.in/yaml.v1"
 )
 var data = `
 a: Easy!
 b:
  c: 2
  d: [3, 4]
 `
 type T struct {
        A string
        B struct{C int; D []int ",flow"}
 }
 func main() {
        t := T{}
        err := yaml.Unmarshal([]byte(data), &t)
        if err != nil {
                log.Fatalf("error: %v", err)
        }
        fmt.Printf("--- t:\n%v\n\n", t)
        d, err := yaml.Marshal(&t)
        if err != nil {
                log.Fatalf("error: %v", err)
        }
        fmt.Printf("--- t dump:\n%s\n\n", string(d))
        m := make(map[interface{}]interface{})
        err = yaml.Unmarshal([]byte(data), &m)
        if err != nil {
                log.Fatalf("error: %v", err)
        }
        fmt.Printf("--- m:\n%v\n\n", m)
        d, err = yaml.Marshal(&m)
        if err != nil {
                log.Fatalf("error: %v", err)
        }
        fmt.Printf("--- m dump:\n%s\n\n", string(d))
 }
 ```
 This example will generate the following output:
 ```
 --- t:
 {Easy! {2 [3 4]}}
 --- t dump:
 a: Easy!
 b:
  c: 2
  d: [3, 4]
 --- m:
 map[a:Easy! b:map[c:2 d:[3 4]]]
 --- m dump:
 a: Easy!
 b:
  c: 2
  d:
  - 3
  - 4

 GoSerial
 ========
 A simple go package to allow you to read and write from the
 serial port as a stream of bytes.
 Details
 -------
 It aims to have the same API on all platforms, including windows.  As
 an added bonus, the windows package does not use cgo, so you can cross
 compile for windows from another platform.  Unfortunately goinstall
 does not currently let you cross compile so you will have to do it
 manually:
    GOOS=windows make clean install
 Currently there is very little in the way of configurability.  You can
 set the baud rate.  Then you can Read(), Write(), or Close() the
 connection.  Read() will block until at least one byte is returned.
 Write is the same.  There is currently no exposed way to set the
 timeouts, though patches are welcome.
 Currently all ports are opened with 8 data bits, 1 stop bit, no
 parity, no hardware flow control, and no software flow control.  This
 works fine for many real devices and many faux serial devices
 including usb-to-serial converters and bluetooth serial ports.
 You may Read() and Write() simulantiously on the same connection (from
 different goroutines).
 Usage
 -----
 ```go
 package main
 import (
        "github.com/tarm/goserial"
        "log"
 )
 func main() {
        c := &serial.Config{Name: "COM45", Baud: 115200}
        s, err := serial.OpenPort(c)
        if err != nil {
                log.Fatal(err)
        }
        n, err := s.Write([]byte("test"))
        if err != nil {
                log.Fatal(err)
        }
        buf := make([]byte, 128)
        n, err = s.Read(buf)
        if err != nil {
                log.Fatal(err)
        }
        log.Print("%q", buf[:n])
 }
 ```
 Possible Future Work
 -------------------- 
 - better tests (loopback etc)
