archiso

The archiso project features scripts and configuration templates to build installation media (.iso images) for BIOS and UEFI based systems on the x86_64 architecture. Currently creating the images is only supported on Arch Linux.

Requirements

The following packages need to be installed to be able to create an image with the included scripts:

• arch-install-scripts
• dosfstools
• e2fsprogs
• edk2-shell
• libisoburn
• squashfs-tools

For running the images in a virtualized test environment the following packages are required:

• edk2-ovmf
• qemu

For linting the shell scripts the following package is required:

• shellcheck

Profiles

Archiso comes with two profiles: baseline and releng. While both can serve as starting points for creating custom live media, releng is used to create the monthly installation medium. They can be found below configs/baseline/ and configs/releng/ (respectively). Both profiles are defined by files to be placed into overlays (e.g. airootfs -> the image's /) and dynamic actions (i.e. build.sh scripts).

Create images

Usually the archiso tools are installed as a package. However, it is also possible to clone this repository and create images without installing archiso system-wide.

As filesystems are created and various mount actions have to be done when creating an image, root is required to run the scripts.

When archiso is installed system-wide and the modification of a profile is desired, it is necessary to copy it to a writeable location, as /usr/share/archiso is tracked by the package manager and only writeable by root (changes will be lost on update).

The examples below will assume an unmodified profile in a system location (unless noted otherwise).

It is advised to check the help information of the build.sh scripts in the profiles:

/usr/share/archiso/configs/releng/build.sh --help

Create images with packaged archiso

/usr/share/archiso/configs/releng/build.sh -w path/to/work_dir -o path/to/out_dir

Create images with local clone

Clone this repository and make sure to run with the local mkarchiso script in PATH (if it has been modified):

PATH="archiso:$PATH" ./configs/releng/build.sh -w path/to/work_dir -o path/to/out_dir

Testing

The convenience script run_archiso is provided to boot into the medium using qemu. It is advised to read its help information:

run_archiso -h

Run the following to boot the iso using BIOS:

run_archiso -i path/to/an/arch.iso

Run the following to boot the iso using UEFI:

run_archiso -i path/to/an/arch.iso -u

The script can of course also be executed from this repository:

./scripts/run_archiso.sh -i path/to/an/arch.iso

Installation

To install archiso system-wide use the included Makefile:

make install

Optionally install archiso's mkinitcpio hooks:

make install-initcpio
