Install Order

Order of installation

The Stacki XML framework is called Stacki Universal XML. To explain how SUX is structured, we first have to understand the process of installation of a backend node.

Order of Installation

When the network auto-installer (anaconda, autoyast, preseed) performs the OS installation, it does it in the following order.

1. Hardware Probing - The installer starts by probing the hardware and enumerates all the devices.

2. Network setup - The installer then configures the network with IP address, netmask, and gateway information

3. Kickstart/yast/preseed Retrieval - The installer retrieves the auto-install file from the frontend that provides it with instructions on how to proceed with the installation.

4. Main section - The installer configures timezones, root passwords, etc. This section typically includes Kickstart directives.

5. Pre section - This section consists of instructions to be run before the partitioning, and package installation. This typically is used to setup the installer environment so that partitioning may be changed. This section is typically coded in shell, or python.

6. Storage setup and build - If a storage configuration has been set, the installer defines and implements the storage controller config on any supported controller card. (LSI)

7. Disk setup and partitioning - Next, the installer configures the disks attached to the system, partitions them, formats them and makes them available to the installer.

8. Package Installation - This section contains a list of packages to be installed on the system.

9. Post Section - This section consists of instructions to be run after package installation. This section may be coded in any interpreted language that is available on the installed system.

10. Pre-boot Section - This section is run on first-boot before any services or daemons are started.

11. Post-Boot Section - This section is a collection of shell scripts that are run on first-boot after all services and daemons have started. This is typically used to run scripts that interact with system daemons, or to finish and clean-up the installation process.
