To date the iso version was used for iso volume information and iso file name.
In my custom builds I do use it a lot more:
* Inside the root fs: The system knows about its own version. I use this to:
-> report the version to a server (poor man's inventory)
-> let the system update itself
* On the iso fs: The files are served via rsync, running systems transfer
version file first to check for available update.
* A grub environment file on the iso fs: Booting the iso from grub allows
to create cow directory per version:
loopback loop archlinux.iso
load_env -f (loop)/arch/grubenv
linux (loop)/arch/boot/x86_64/vmlinuz-linux ... \
cow_directory=archlinux/${VERSION} ...
So let's just create these files.

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
|
|
* libisoburn
|
|
* mtools
|
|
* 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/ <configs/baseline/>`_ and `configs/releng/ <configs/releng/>`_
|
|
(respectively). Both profiles are defined by files to be placed into overlays (e.g. *airootfs* -> *the image's /*).
|
|
|
|
Read `README.profile.rst <README.profile.rst>`_ to learn more about how to create profiles.
|
|
|
|
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 consult the help output of **mkarchiso**:
|
|
|
|
.. code:: bash
|
|
|
|
mkarchiso -h
|
|
|
|
Create images with packaged archiso
|
|
-----------------------------------
|
|
|
|
.. code:: bash
|
|
|
|
mkarchiso -w path/to/work_dir -o path/to/out_dir path/to/profile
|
|
|
|
Create images with local clone
|
|
------------------------------
|
|
|
|
Clone this repository and run:
|
|
|
|
.. code:: bash
|
|
|
|
./archiso/mkarchiso -w path/to/work_dir -o path/to/out_dir path/to/profile
|
|
|
|
Testing
|
|
=======
|
|
|
|
The convenience script **run_archiso** is provided to boot into the medium using qemu.
|
|
It is advised to consult its help output:
|
|
|
|
.. code:: bash
|
|
|
|
run_archiso -h
|
|
|
|
Run the following to boot the iso using BIOS:
|
|
|
|
.. code:: bash
|
|
|
|
run_archiso -i path/to/an/arch.iso
|
|
|
|
Run the following to boot the iso using UEFI:
|
|
|
|
.. code:: bash
|
|
|
|
run_archiso -u -i path/to/an/arch.iso
|
|
|
|
The script can of course also be executed from this repository:
|
|
|
|
|
|
.. code:: bash
|
|
|
|
./scripts/run_archiso.sh -i path/to/an/arch.iso
|
|
|
|
Installation
|
|
============
|
|
|
|
To install archiso system-wide use the included **Makefile**:
|
|
|
|
.. code:: bash
|
|
|
|
make install
|
|
|
|
Optionally install archiso's mkinitcpio hooks:
|
|
|
|
.. code:: bash
|
|
|
|
make install-initcpio
|
|
|
|
Optional Features
|
|
=================
|
|
|
|
The iso image contains a grub environment block holding the iso version. This allows to boot the iso image from grub
|
|
with a version specific cow directory to mitigate overlay clashes.
|
|
|
|
.. code:: grub
|
|
loopback loop archlinux.iso
|
|
load_env -f (loop)/arch/grubenv
|
|
linux (loop)/arch/boot/x86_64/vmlinuz-linux ... \
|
|
cow_directory=archlinux/${VERSION} ...
|
|
initrd (loop)/arch/boot/x86_64/initramfs-linux-lts.img
