# Live Overlay

Files in `iso-profiles/antergos/live-overlay/` exist only in the live environment — they are **not** present after installation.

## Key files

### `etc/calamares-online/settings.conf`

The online install sequence. Defines two `packagechooser` instances:

- `packagechooser@de` — desktop environment selector using `method: netinstall-add`. Writes the selected DE's package group to the `netinstallAdd` global storage key. The DE group is dynamically appended to the netinstall tree when the netinstall module loads.
- `packagechooser@dm` — display manager selector using `method: netinstall-select`. Marks the chosen DM group as checked in the netinstall tree.

The `modules-search: [ local ]` directive resolves module configs from the same directory as the settings file (`/etc/calamares/modules/`).

> There is **no** `settings.conf` at `etc/calamares/` in this overlay. The `/etc/calamares/settings.conf` on a live system is a symlink installed by the `calamares-branding-antergos-next` package (`ln -sf ../calamares-offline/settings.conf`), and `calamares-next.sh` swaps it to the online config at runtime.

### `etc/calamares/modules/` vs `etc/calamares-online/modules/`

- `calamares/modules/` — active module configs at runtime. The settings file resolves modules from this directory after being copied to `/etc/calamares/`.
- `calamares-online/modules/` — reference copies and additional modules (e.g. `partition.conf`, `mount.conf`) that are used during the online install flow. These are not loaded directly but serve as the source of truth for the install sequence.

### `etc/calamares/modules/basestrap.conf`

Controls package installation during bootstrapping. The `operations` list includes packages that must be installed with `--overwrite`. This is where `antergos-release` is listed to ensure it overwrites `/usr/lib/os-release` from the `filesystem` package.

### `etc/calamares-online/modules/*.conf`

Additional modules required for the online install flow:

| File | Purpose |
|------|---------|
| `initcpio.conf` | mkinitcpio generation |
| `locale.conf` | Locale and timezone |
| `mount.conf` | Filesystem mounting |
| `partition.conf` | Disk partitioning |
| `umount.conf` | Unmounting |
| `users.conf` | User creation |
| `welcome.conf` | Welcome page |

### `usr/share/applications/calamares.desktop`

The branded "Install Antergos NeXT" launcher (plus `antergos-offline-install.desktop` for the offline installer). Both run with `sudo -E`. The upstream Artix "Install Artix Linux" entry is hidden via `NoExtract` in `pacman.conf.d/iso-x86_64.conf` (see [Launcher](launcher)).

## Module configs removed

The following files were removed during the transition away from the init system selector:

- `packagechooser.conf` — the old init system selector (dinit/openrc/runit/s6). Replaced by `packagechooser_de.conf` (DE selector).
- `images/` — SVG icons for init systems (dinit.svg, openrc.svg, runit.svg, s6.svg). No longer needed.

These files were removed in commit `6ec25cc` (2026-07-24) when the DE selector landed.

## DE selector package lists

The two copies of `packagechooser_de.conf` differ in their package granularity:

- `calamares/modules/packagechooser_de.conf` — **explicit package lists** (e.g. all 44 Plasma packages listed individually). Users see the full list in the netinstall refinement step.
- `calamares-online/modules/packagechooser_de.conf` — **meta/group packages** (e.g. `plasma`, `xfce4`, `mate`). Simpler but less granular for refinement.

Both use the same DE IDs and `method: netinstall-add`. The active copy at runtime is the one in `calamares/modules/`.
