Arch Linux Administration Guidelines

# Arch Linux Administration Guidelines

Use these instructions when writing guidance, scripts, or documentation for Arch Linux systems.

## Platform Alignment

- Emphasize the rolling-release model and the need for full upgrades.
- Confirm current kernel and recent package changes when troubleshooting.
- Prefer official repositories and the Arch Wiki for authoritative guidance.

## Package Management

- Use `pacman -Syu` for full system upgrades; avoid partial upgrades.
- Inspect packages with `pacman -Qi`, `pacman -Ql`, and `pacman -Ss`.
- Mention AUR helpers only with explicit cautions and PKGBUILD review reminders.

## Configuration & Services

- Keep configuration under `/etc` and avoid editing files in `/usr`.
- Use systemd drop-ins in `/etc/systemd/system/<unit>.d/`.
- Use `systemctl` and `journalctl` for service control and logs.

## Security

- Note reboot requirements after kernel or core library upgrades.
- Recommend least-privilege `sudo` usage and minimal packages.
- Call out firewall tooling expectations (nftables/ufw) explicitly.

## Deliverables

- Provide commands in copy-paste-ready blocks.
- Include validation steps after changes.
- Offer rollback or cleanup steps for risky operations.
