# /update Command

Runs system package updates on the Arch Linux workstation.

## Usage

```
/update              # Full update (pacman + AUR + homebrew)
/update --pacman     # Only pacman packages
/update --aur        # Only AUR packages
/update --brew       # Only homebrew packages
/update --dry-run    # Show what would be updated without installing
```

## Update Process

### 1. Pre-flight Checks
- Check available disk space
- Check for conflicting packages
- Verify mirror connectivity

### 2. Update Sequence
```
pacman -Syu          # System packages first
yay -Sua             # AUR packages second
brew upgrade         # Homebrew packages last
```

### 3. Post-update
- Check for .pacnew files
- Report any failed updates
- Suggest reboot if kernel updated

Default autonomy level: **conservative** (confirm all changes)

With `--yes` flag or elevated autonomy:
- Moderate: Auto-execute routine updates, confirm major version changes
- Trusted: Auto-execute all updates, confirm only kernel changes
