Cannot build an EL 8.3 system via Satellite Bootdisk or Discovery kexec
Dracut in PXE images for RHEL 8.3 no longer accepts hardware type prefix in the BOOTIF kernel command line parameter. Foreman PXE/Grub2 templates adds BOOTIF with the prefix (e.g. BOOTIF=00-AA-BB-CC-DD-EE-FF) which leads to failure because NIC is not properly initialized. For PXELinux
IPAPPEND 2 statement must be also removed because it automatically generates and appends BOOTIF statement with the prefix.
We need to implement a workaround in PXELinux, iPXE and Grub templates for this specifically for EL 8.3 or EL 8.3+ if this turns out to be expected behavior.
