Feature #12634

Updated by Lukas Zapletal over 4 years ago

Hardware model will Host and hostgroups must be enhanced with two new flags: PXE template specifies
PXE template kind and variant pair to use. Until today, this was hardcoded to
PXELinux or PXEGrub by selected operating system. Optionally, template variant
flag from OS could be simply dropped because PXE template implies variant to
use and there are no variants which share the same configuration syntax (this
is an open item).

Orchestration TFTP code must be modified to use multiple "KIND LOADER default
local boot" and "KIND LOADER global default" templates. Local and global boot
templates must be added for Grub2 new kind. Naming convention will be:

* PXELinux BIOS default local boot
* PXELinux UEFI default local boot
* PXEGrub BIOS default local boot
* PXEGrub UEFI default local boot
* etc. (the same for global default templates)

But only kind/variant is not enough, users need to select BIOS or UEFI booting
method. This is where Loader flag comes in - selection of three constants:
BIOS, UEFI and SecureBoot UEFI. The first two are obvious causing selection of
the correct DHCP filename when deploying TFTP configuration, the third one
select "shim.efi" chain loading capability for secure booting.

Hardware model fact importing will be enhanced - it will be possible Similarly to import
the loader flag from an extra custom fact (defined via
root password, a global settings).
setting could be provided for one or both flags for missing values (open item).
