 Using a higher number of rounds will help create more secure passwords, but given enough time, password hashes can be reversed.  On most RPM based distributions there is a tool called mkpasswd available in the `expect` package, but this does not handle "rounds" nor advanced hashing algorithms. 
 
+#### Retrieving ssh authorized keys from a GitHub user
+
+Using the field `coreos-ssh-import-github` you can make coreos-cloudinit to add the public ssh keys from a GitHub user as authorized keys to a server.

+#cloud-config
+
+users:
+  - name: elroy

+
+#### Retrieving ssh authorized keys from an http endpoint
+
+coreos-cloudinit can also pull public SSH keys from any http endpoint that matches [GitHub's API response format](https://developer.github.com/v3/users/keys/#list-public-keys-for-a-user).
+For example, if you have an installation of GitHub Enterprise, you can provide a complete url with an authentication token:
+
+```
+#cloud-config
+
+users:
+  - name: elroy
+    coreos-ssh-import-url: https://token:<OAUTH-TOKEN>@github-enterprise.example.com/users/elroy/keys
+```
+
+You can also provide any url which response matches that json format for public keys:
+
+```
+#cloud-config
+
+users:
+  - name: elroy
+    coreos-ssh-import-url: https://example.com/public-keys

+The only supported value is "localhost" which will cause your system's hostname

+# Distribution via Config Drive
+
+CoreOS supports providing configuration data via [config drive][config-drive]
+disk images. Currently only providing a single script or cloud config file is
+supported.
+
+[config-drive]: http://docs.openstack.org/user-guide/content/enable_config_drive.html#config_drive_contents
+
+## Contents and Format
+
+The image should be a single FAT or ISO9660 file system with the label
+`config-2` and the configuration data should be located at
+`openstack/latest/user_data`.
+
+For example, to wrap up a config named `user_data` in a config drive image:
+
+    mkdir -p /tmp/new-drive/openstack/latest
+    cp user_data /tmp/new-drive/openstack/latest/user_data
+    mkisofs -R -V config-2 -o configdrive.iso /tmp/new-drive
+    rm -r /tmp/new-drive
+
+## QEMU virtfs
+
+One exception to the above, when using QEMU it is possible to skip creating an
+image and use a plain directory containing the same contents:
+
+    qemu-system-x86_64 \
+        -fsdev local,id=conf,security_model=none,readonly,path=/tmp/new-drive \
+        -device virtio-9p-pci,fsdev=conf,mount_tag=config-2 \
