Ok - so I discovered that while I boot autoinstall with the "biosdevname=0
net.ifnames=0" - this does NOT - automatically get set during the install
and then reboot.
If I login and manually add them to the /etc/default/grug file and reboot
it works.  So question then is how do my "late-commands" - update the
/etc/default/grub ?

I found an example where it using /target and curtin in-target --target
/target update-grub - - --- WOW - can I not do "chroot /target" and just
have normal commands ?
