ArchISO

Installation

sudo pacman -S archiso

Prepare a custom profile

To adapt or customize one of archiso's shipped profiles, copy it from /usr/share/archiso/configs/profile-name/ to a writable directory with a name of your choice:

cp -r /usr/share/archiso/configs/releng/ ~/dev/arch/archiso

Profile structure

The profile structure is documented in /usr/share/doc/archiso/README.profile.rst

Select packages

Edit packages.x86_64 to select which packages are to be installed on the live system image, listing packages line by line.

Custom local repository

To add packages not located in standard Arch repositories (e.g. custom packages or packages from AUR/ABS), set up a custom local repository and add your custom packages to it.

Then add your repository to ~/dev/archiso/pacman.conf as follows:

[customrepo]
SigLevel = Optional TrustAll
Server = file:///path/to/customrepo

Note:

  • The ordering within pacman.conf matters. To give top priority to your custom repository, place it above the other repository entries.
  • This pacman.conf is only used for building the image. It will not be used in the live environment. To do this, see #Adding repositories to the image.

Add files to the image

The airootfs directory is used as the starting point for the root directory / of the live system on the image. All its contents will be copied over to the working directory before packages are installed.

Place any custom files and/or directories in the desired location under airootfs/. For example, if you have a set of iptables scripts on your current system you want to be used on you live image, copy them over as such:

cp -r /etc/iptables archiso/airootfs/etc

Tip: To add a file to the install user's home directory, place it in archiso/airootfs/root/. To add a file to all other users home directories, place it in archiso/airootfs/etc/skel/.

By default, permissions will be 644 for files and 755 for directories. All of them will be owned by the root user.
