Omarchy ISO

The Omarchy ISO is the only supported way to install Omarchy. It ships the Omarchy Configurator, installs Arch Linux, installs the Omarchy packages from the bundled mirror, runs target system setup in the chroot, creates the user, and runs omarchy-setup-user for that user.

Downloading the latest ISO

See the ISO link on omarchy.org.

Creating the ISO

Run ./bin/omarchy-iso-make; output goes into ./release. By default the ISO uses the Omarchy packages and tracks the quattro branch, from the stable mirror. Pass --edge to use omarchy-dev and omarchy-settings-dev from the edge mirror.

For local development, build the ISO from sibling checkouts:

./bin/omarchy-iso-make --local-source ../omarchy-installer ../omarchy-pkgs

Despite the local folder name, the first argument is the Omarchy source checkout (runtime commands, configs, setup scripts, themes, shell, migrations). The installer itself lives in this ISO repo.

Use --dev or --rc to build against those package channels. Both --dev and --edge select the dev packages from the edge mirror.

Testing the ISO

Run ./bin/omarchy-iso-boot [release/omarchy.iso].

To exercise installation alongside existing Windows-style partitions, run ./bin/omarchy-iso-test-windows-disk [release/omarchy.iso]. It creates a synthetic disk in /tmp with an existing ESP and data partition plus ample unallocated space, then offers to start an interactive installation on it. The fixture exercises Windows partition preservation but does not contain Windows.

Acceptance testing the ISO

Run ./bin/omarchy-iso-test [release/omarchy.iso] to install the ISO into a headless VM by driving the real interactive install flow — the harness reads each screen via QMP screendumps + OCR and answers with virtual keystrokes, so the configurator wizard, install dashboard, reboot prompt, and SDDM login are all exercised exactly as a user would. It then boots the installed system and runs the in-guest acceptance suite (test/acceptance in the omarchy repo): session health, application launches, and shell surfaces like the launcher and emoji picker. Screenshots, serial logs, and the install log land in test-runs/<iso>/runs/<timestamp>/.

The install phase produces a reusable base image, so iterating on the suite is fast:

./bin/omarchy-iso-test release/omarchy.iso --install-only        # once per ISO
./bin/omarchy-iso-test release/omarchy.iso --reuse-base \
  --sync-omarchy ../omarchy-installer                            # fast loop against local tests

Pass --encrypt to drive the encrypted install flow (including typing the LUKS passphrase at boot) instead of the unencrypted one.

Signing the ISO

Run ./bin/omarchy-iso-sign [release/omarchy.iso]. The signing key is retrieved from the shared Omarchy vault with the 1Password CLI.

Uploading the ISO

Run ./bin/omarchy-iso-upload [release/omarchy.iso]. This requires rclone configuration (rclone config).

Full release of the ISO

Run ./bin/omarchy-iso-release VERSION to create, test, sign, and upload the ISO in one flow. Add --rc to release an RC build instead.
