Yes, its possible. Is the question essentially: How-To avoid re-creating the image, yet still have flexible autoinstall.yaml at boot-time? 1. Autoinstall configuration reference manual - Ubuntu installation documentation: https://canonical-subiquity.readthedocs-hosted.com/en/latest/reference/autoinstall-reference.html#early-commands autoinstall: # Pause the install just before starting to allow manual inspection/modification of the live system. # Unpause by creating the /run/finish-early" file. early-commands: - while [ ! -f /run/finish-early ]; do sleep 1; done autoinstall: # Replace the current autoinstall configuration with one provided by a trusted server early-commands: - wget -O /autoinstall.yaml $TRUSTED_SERVER_URL Supplying files during install w/o network, but by using an addendum “install driver update disk”. 2. How to Set Boot Parameters for the Different Linux Distributions : https://lenovopress.lenovo.com/lp1703.pdf Common parameters This section introduces some common but ambiguous parameters and debug settings of GRUB2. The following is the list of common parameters about different distributions. Driver update parameters: RHEL: inst.dd=hd:LABEL=DISK_LABEL:/DRIVER.rpm inst.dd=http://IP/PATH/DRIVER.rpm SLES: dud=disk:/DRIVER.dud dud=http://IP/PATH/DRIVER.dud insecure=1 Ubuntu: debian-installer/driver-update= Could these option help? - Allan ----- Original Message ----- From: Jean-Francois Messier via linux <linux [ at ] linux-ottawa [ dot ] org> To: linux [ at ] linux-ottawa [ dot ] org Sent: Tue, 19 Aug 2025 12:18:23 -0400 (EDT) Subject: Re: [linux] time to clarify my (mis)understanding of ubuntu autoinstall.yaml Not sure whether this would work with Ubuntu, but for Red Hat, you could mount a separate ISO file as a secondary CDROM, or a Floppy image containing the autoinst.yaml and it would install it as per this YAML file. Please correct me if I'm wrong. As for not re-creating a whole new ISO file, I think Robert is right. Unless, of course you have new packages you also need to be added to the ISO.
