Kernel and Initrd

Download Ubuntu ISO and extract kernel and initrd

wget https://releases.ubuntu.com/22.04.3/ubuntu-22.04.3-live-server-amd64.iso

mkdir /mnt/ubuntu

mkdir /var/lib/tftpboot/boot/ubuntu22

mount ubuntu-22.04.3-live-server-amd64.iso /mnt/ubuntu

cp /mnt/ubuntu22/casper/vmlinuz /var/lib/tftpboot/boot/ubuntu22/

cp /mnt/ubuntu22/casper/initrd /var/lib/tftpboot/boot/ubuntu22/

Make the ISO available in the network

In my case I have different Operating Systems to provision with Foreman, for that I have a virtual machine with the intallation ISO's.

dnf install -y httpd systemctl enable --now httpd mkdir -p /var/www/html/pub/ubuntu22 cp ubuntu-22.04.3-live-server-amd64.iso /var/www/html/pub/ubuntu22/
