Installation

Network Installation

The machine you want to install needs to be registered in sysdb. To be on bleading edge, you might select the rhel8_preprod Puppet environment:

FQDN=...
bob node set-attr $FQDN puppet_env=rhel8_preprod

Optional you can set netboot and RHEL 8.6 installer but that can also be selected manually in be boot menu:

bob node netboot $FQDN
bob node set-attr $FQDN ipxe_installer=rhel86install

Installation with UEFI

Start the machine and select network boot (if not already the default), then you get following menu:
Grub default menu

There select "Install Red Hat Enterprise Linux 8.6" Grub menu selection for iPXE

Installation with Legacy BIOS

Start the machine and select network boot (if not already the default), then you get following menu:
PXE default menu

There select "Red Hat Enterprise Linux 7 Network Install Menu" to get into the iPXE menu, where you can do also a lot of other stuff.
PXE menu selection for iPXE
(I plan to get rid of above menu as it also breaks automatic installation by sysdb configuration).

The iPXE menu is then generated according to sysdb and its default depends on the configuration, there, but you may override it manualy:
iPXE menu with local boot default

select RHEL 8 installation
