This is not a discussion about netplan, I just want to craft an iso that has netplan disabled.
The FAQ (https://netplan.io/faq#how-to-go-back-to-ifupdown) says "[...]This is done by adding the preseed line to the command line when booting the installation media[...]"
I repacked the current Ubuntu 18.04.1 server image and changed the boot/grub/grub.cfg to not use netplan. But for some reason that is not working.
menuentry "Install Ubuntu Server" {
set gfxpayload=keep
linux /install/vmlinuz file=/cdrom/preseed/ubuntu-server.seed quiet netcfg/do_not_use_netplan=true ---
initrd /install/initrd.gz
}
Can someone tell what I did wrong? How to get this to work?
