# Implementation Instructions for Codex

## Goal

Improve the installer's robustness while preserving behavior on a fresh
Omarchy installation.

## 1. Make system updates optional (High Priority)

Current behavior:

``` bash
yay -Syu --noconfirm
```

Problem: - Fresh Omarchy installs are already up to date. - Adds
unnecessary install time. - Can fail because of mirrors or package
updates. - Makes installs less reproducible.

Required change: - Do **not** update the system by default. - Introduce
an environment variable:

``` bash
UPDATE_SYSTEM=1 ./install.sh
```

Behavior: - If `UPDATE_SYSTEM=1`, run:

``` bash
yay -Syu --noconfirm
```

-   Otherwise skip the full upgrade.

------------------------------------------------------------------------

## 2. Verify required commands exist (High Priority)

Before any installation begins, verify required tools exist.

Minimum:

-   yay
-   git
-   systemctl
-   fc-cache
-   flatpak

Example:

``` bash
command -v yay >/dev/null || {
    echo "yay is required."
    exit 1
}
```

Fail early with clear error messages.

------------------------------------------------------------------------

## 3. Install packages individually (High Priority)

Current behavior: - One package failure aborts the installer because of
`set -e`.

Desired behavior: - Continue installing remaining packages. - Report
failures at the end.

Pseudo-code:

``` bash
failed_packages=()

for pkg in "${packages[@]}"; do
    if ! yay -S --needed --noconfirm "$pkg"; then
        failed_packages+=("$pkg")
    fi
done
```

Print a summary if any packages failed.

------------------------------------------------------------------------

## 4. Remove duplicate packages (Medium Priority)

Some packages currently appear in multiple package lists.

Deduplicate package sources so each package exists only once.

------------------------------------------------------------------------

## 5. Improve service enabling (Medium Priority)

Current implementation checks service existence before enabling.

Instead:

``` bash
sudo systemctl enable SERVICE || true
```

or use a more reliable existence check.

Goal: - Never abort because one optional service is unavailable.

------------------------------------------------------------------------

## 6. Document directory symlink behavior (Low Priority)

Entire config directories are symlinked.

This is acceptable, but document that: - Future Omarchy config additions
inside those directories will not appear automatically. - This is an
intentional trade-off.

No implementation change required unless desired.

------------------------------------------------------------------------

## 7. Consider copying fonts instead of symlinking (Low Priority)

Current behavior: - Font directory is symlinked.

Consider: - Copying fonts into the user's font directory. - Run
`fc-cache -fv` afterward.

If symlinks are kept, document why.

------------------------------------------------------------------------

## 8. Verify Flathub exists before Flatpak installs (Medium Priority)

Before installing Flatpak packages, ensure the Flathub remote exists.

If missing: - Add Flathub automatically. - Continue installation.

------------------------------------------------------------------------

## 9. Do not distribute the Git metadata (Low Priority)

When publishing releases or ZIP archives: - Exclude the `.git`
directory. - Ship only the working tree.

No installer changes required.

------------------------------------------------------------------------

# Desired Characteristics

The installer should remain:

-   idempotent
-   safe to rerun
-   backup existing configs
-   continue after non-critical failures
-   easy to understand
-   optimized for fresh Omarchy installations

The default install path should be fast, deterministic, and require
minimal user interaction.
