Add the ability to deploy installer systems and add examples.baserock/pedroalvarez/installer6
The installer-x86_64 system is a system that can be used to install other systems in an storage device. This system is intended to be booted by usb, pxeboot... to install a Baserock system in your local disk. The installer system requires the installer.configure extension to generate a configuration file located in /etc/install.conf. With this extension you can specify the following variables in a cluster morphology: - INSTALLER_TARGET_STORAGE_DEVICE: Target storage device to install the Baserock system. - INSTALLER_ROOTFS_TO_INSTALL: The location of the root filesystem that is going to be installed. - INSTALLER_POST_INSTALL_COMMAND: Commands that will be run after the installation finishes. It defaults to `reboot -f`. The installer-utils stratum is required to contain the installer-scripts chunk. This chunk contains the installer script that is going to be installed in /usr/lib/installer/installer.py The clusters/installer-build-system-x86_64.morph file defines the deployment of a installer system as a rawdisk image. This installer system will install a build-system-x86_64 located in /rootfs into the /dev/sda device. Also this cluster defines a subsystem which is the build-system that is going to end up in /rootfs on the installer system.

+description: |
+ This is a cluster morphology that can be used to deploy
+ installer systems. This is done by adding the files needed
+ using a manifest file (installer/manifest) with the INSTALL_FILES
+ extension, and using the installer.configure extension to generate
+ the configuration needed in the system.
+
+ This manifest, which is installing the installer script in
+ /usr/lib/installer/installer.py, in combination of adding
+ "init=/usr/lib/installer/installer.py" as KERNEL_ARGS in the system
+ makes the system run the installer.py script as init script.
+
+ The installer.py script will read the information needed to
+ install the system (where is the root filesystem to install and
+ where to install it) from /etc/install.conf.
+
+ This cluster also deploys a subsystem (a build-system in this case)
+ which is going to be the system that the installer system/script is
+ going to install.
