ubuntu-20.04.3-install

AlmaLinux-8 installer that points to the latest Alma 8 release.

Install Ubuntu Focal Fossa (20.04.3) LTS version. This BootEnv will install the General Available (GA) kernel.

Note

Default Ubuntu ISOs will attempt to check internet repositories, this can cause problems during provisioning if your environment does not have outbound access. Workaround this by defining Options 3 (Gateway) and 6 (DNS) for your Subnet settings. See https://docs.rackn.io/stable/resources/kb/kb-00033/

The Param named part-scheme can be used to inject a storage section. Set the param to a value that will be used to locate a template containing the YAML storage definition.

The template would be named "part-scheme-<Value of part-scheme>.tmpl".

The format should be:

# Note Indentation matters with the extra two spaces.
  storage:
    swap:
      size: 0
    layout:
      name: direct
      match:
        ssd: yes

Documentation for storage format and options can be found at:

The Ubuntu 20.04 enforced UEFI boot re-ordering can be corrected by adding this additional stanza to the storage YAML structure:

# Note Indentation matters with the extra two spaces.
  storage:
    grub:
      reorder_uefi: False

Note

If any storage definition is used, then the all options for setting disk partitioning must be used. The above UEFI disable can not be used on it's own without additional disk configuration.
