PXELinux and Grub2 exists as BIOS (Legacy) and UEFI. Is this 5 kinds or 3 kinds x 2 flavors?

The latter, we aim to support both BIOS and EFI systems with either PXELinux and Grub (becaue of RHEL6 support) or PXELinux and Grub2. The goal is to deploy PXE files simultaneously so both systems can be booted up.

I mean, Foreman will be able to deploy all three at once, but only two of the three will be likely used for one deployment. Grub1 is legacy, the PXE configuration will be present, but DHCP will hand over usually PXELinux and/or Grub2 on modern systems (RHEL7+).

Subject changed from Changes in orchestration code to support multiple kinds to New host/hostgroup flags pxe_template and loader

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).

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.

Similarly to root password, a global setting could be provided for one or both flags for missing values (open item).

I'm not sure "booting method" is needed. At least, BIOS or UEFI can be differentiated from DHCP options. See "if option arch" at <https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Installation_Guide/s1-netboot-pxe-config-efi.html>.

Would be nice if there was a custom option added to this so people who want to bypass pxelinux, can. We do not use pxelinux, we load undionly (or whatever we need based on the host, undionly.pxe/kpxe/kkpxe, ipxe.lkrn, etc) and then chain right into iPXE. If I understand correctly, even with this change we will still end up manually editing foreman source code to suit our needs.

What about a custom option that accepts a string so people can load their own pxe images?

We currently implemented that as a fixed list with "None" option.

I'd rather see a patch that will allow loading one or more custom entries from foreman.yaml file (name and filename pairs). Free form is little bit dangerous (e.g. security considerations etc). Feel free to provide a patch, should be easy to do.
