I successfully was able to autoinstall Ubuntu Server 22.04 by calling following GRUB commands. <my-server> provides a user-data config file where users will be created etc.
linux /casper/vmlinuz
autoinstall ds=nocloud-net;seedfrom=<my-server>/ ---
boot
Is it possible to do the same for Lubuntu 22.04?
Lubuntu doesn't seem to respect the autoinstall command. Instead, it directly boots into live mode.
If not, I guess my best option is to stick to Ubuntu Server and just install all packages Lubuntu comes with. Or is there a simpler approach?
