Create utility to generate hybrid bootloader from ISO
The gen-bootloader-iso.sh utility takes a StarlingX installation ISO as input and generates a small bootloader ISO and www-served directory structure to provide a hybrid ISO/network installation ISO. The utility sets up two structures under the specified www-root directory: shared files and node-specific files Shared files: These are the rootfs (squashfs.img) and software package repositories that will be downloaded to the installing node via http/https, and would be common to all nodes being installed. Node-specific files: These include: - a much smaller bootimage.iso that contains the kernel and initrd, as well as syslinux.cfg and grub.cfg files updated to access rootfs, repos, and the node-specific kickstart file, via https (rather than from the ISO). - a generated kickstart specific for the node which gets the software to be installed from http/https, and can have a node-specific %post section. - symbolic links to shared files, for http/https access. The utility also provides file cleanup functionality with the --delete option, which will remove the node-specific files. If all node files have been removed, it will also remove the shared files.

Description: Sets up a mini bootimage.iso that includes the minimum required to
|
||||
retrieve the rootfs and software packages needed for installation via http or
|
||||
https, generated for a specific node.
|
||||
|
||||
Mandatory parameters for setup:
|
||||
--input <file>: Specify input ISO file
|
||||

|
||||
--boot-ip <ip address>: Specify address for boot interface
|
||||
--default-boot <0-5>: Specify install type:
|
||||
