How to build i386 images

Purpose

This guide describes how to build a 32 bit TDE live system.

The main difference is the build container usage, so you can prepare source and target directories just like the amd64 image.

Prepare the build container

Create the container for the build enviroment:

$ sudo podman build --arch=i386 --build-arg REGISTRY_PREFIX=docker.io/i386 \
--file=/<source-path>/Containerfile --tag=tdebuild:i386

Initialize the container by running an interactive shell:

$ sudo podman run --arch=i386 --privileged --network=host -it \
--volume=/<source-path>:/live/source:ro --volume=/<target-path>:/live/target \
--name=tdebuild-i386 --hostname=tdebuild-i386 tdebuild:i386 /usr/bin/bash

Exit from the build container. To enter again into the build container:

$ sudo podman start -ia tdebuild-i386

Build the image

First, start the build container if not running:

$ sudo podman start tdebuild-i386

Build the .iso image by running the kiwi-ng command:

$ sudo podman exec tdebuild-i386 linux32 kiwi-ng --profile=Workstation-l10n --type=iso \
--debug --color-output --shared-cache-dir=/live/target/cache system build \
--description=/live/source/kiwi-descriptions --target-dir=/live/target

Patch the built image

The resulting image is not bootable. In order to get it bootable, run the following command:

$ sudo podman exec tdebuild-i386 xorriso -indev /live/target/TDE-Remix.ix86-<version>.iso \
-outdev /live/target/TDE-Remix.i386.iso -publisher TDE_Remix \
-boot_image grub bin_path=boot/ix86/loader/eltorito.img \
-boot_image grub grub2_mbr=/lib/grub/i386-pc/boot_hybrid.img \
-boot_image any grub2_boot_info=on -boot_image any boot_info_table=on \
-boot_image any platform_id=0x00 -boot_image any emul_type=no_emulation \
