As part of my documentation effort for live-manual, I would like to include the procedure for the official Debian CD image generation (which will effectively replace chapter 16) in https://live-team.pages.debian.net/live-manual/html/live-manual/procedures.en.html This mail is rather technical, but I want to document the steps that I've taken. From what I've seen in the live-setup repository [5], there are two strategies for generating Debian CD images. A) Use lb config (run-30live-build) B) Use lwr (run-30live-wrapper) I downloaded 'debian-live-10.3.0-amd64-standard.iso' from [1], which contains the string 'Official Debian GNU/Linux Live 10.3.0 standard 2020-02-08T12:27'. This string is generated by the run-30live-wrapper script, so I assume that the official images are generated by method B, lwr. I've read through run-30live-wrapper, and I think by now I have correctly extracted the commands for the generation of the Debian Stable CDs, but I'm unsure how to proceed. I have the following questions/requests: * lwr depends on vmdebootstrap, which is currently only in Buster (stable). According to its author vmdebootstrap is to be replaced by vmdb2 or something else [2]. Is someone working on this? * I've seen a huge speed-up when I'm using a ramdisk, but that needs a merge request to be accepted [3]. When invoking 'chroot' in live-setup/available/live-customise.sh the variable TMPDIR must not be set, otherwise it is not possible to generate temporary files within the chroot. * To reduce the amount of downloads, I am using a slightly patched version of apt-cacher-ng, in order to be able to use the installer. See my bug report [4] The live-wrapper script downloads the installer, but apt-cacher-ng rejects a path ending in a slash. The following command simulates this download: <pre> wget -S "http://localhost:3142/deb.debian.org/debian/dists/buster/main/installer-amd64/current/images/cdrom/"; </pre> * The run-30live-wrapper mentions wheezy and jessie, so it is rather old I would like to add to the live-manual the steps to build an image from the current stable and testing versions of Debian. Do you have hints/ideas how I can proceed?
