#### Comments

This is a clean up and custom rewrite of the [OpenNebula](https://opennebula.io/) [contextualization scripts](https://github.com/OpenNebula/addon-context-linux) that provide contextualization in a guest system for an image. In this case the original package is not being used because it was created with "main" distributions in mind (redhat-alike, debian-alike).

Contextualization in OpenNebula tries to keep it simple (it doesn't want to be cloud-init). Everytime the context of the VM is changed, an ISO is generated and loaded into the VM. A `udev` rule then restarts the service, which in its turn runs the scripts that reconfigure the system. 

OpenNebula tries to be distribution agnostic so most scripts are written in shell (I know it goes against the rules), but they provide added value. The package also provides the ruby-written `onegate` command that gathers information about different elements running in a virtual infrastructure.

Its dependencies would be:
- `jq` is used to parse some `iproute2` commands
- `curl` for reporting that the VM is ready
- `ruby` for onegate (script that gathers information from the virtualization system)
- `qemu-ga`, the qemu guest agent for the VM

Thank you

+# OpenNebula contextualization package
+# # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # #
+
+This package provides the necessary scripts to configure automatically 
+the system via OpenNebula contextualization.
+
+To enable it in a clean installation:
+
+- Enable service `one-contextd`:
+  # ln -s /etc/sv/one-contextd /var/service
+
+- Enable service `qemu-ga`:
+  # ln -s /etc/sv/one-contextd /var/service
+
+- Execute onesysprep
+
+After this, use the image for a template.
+

+
+NETWORKING NOTES
+
+For other distributions OpenNebula does rely on it (i.e. networkd, 
+NetworkManager, etc.). 
+
+As Void linux gives you freedom to choose the way you want to 
+configure your network and OpenNebula likes to keep things simple, 
+this contextualization package will generate just the necessary 
+iproute2 commands to configure it. 
+
+This contextualized network config is stored in `/etc/network_config`
+and will be regenerated every time the context changes.
