(Mobile right now, all from the top of my head.)

For the installation, you need to get the boot parameters
("biosdevname=0 net.ifnames=0") on the kernel commandline (either
manually or by baking a custom image) or use the alternative ways for
each (which I don't know by heart, IIRC for PNIN you have to remove or
create some udev file, should be explained in the URL of my earlier
message; CNDN was somewhat similar IIRC).

For the installed system, if you choose to use the boot parameters,
you need to get them into grub.cfg:
- in 13.1 by patching /etc/default/grub for future kernels and
/boot/grub2(?)/grub.cfg for the current kernel, or run "grub2-mkconfig
-o /boot/grub2(?)/grub.cfg"[0] for the latter after you've patched
/etc/default/grub;
- for 12.3 I don't remember if the former or the following
instructions will work;
- for previous oS releases use /etc/sysconfig/bootloader instead of
/etc/default/grub).

0: Although this alternative might not work; I haven't yet figured out
how exactly GRUB config creation works, IIRC /etc/default/grub or
/etc/sysconfig/bootloader contains a comment to the effect of
something like "If there are custom parameters in grub.cfg, they will
be taken from there (or merged with those in /etc/default/grub), else
they will be taken from /etc/default/grub."

For the custom image for stage1 I can give you a crude script. For the
installed system (stage 2 and later), I'm still working on the 13.1
(and maybe 12.3, too) variant.
