Arch Linux Philosophy: The Arch Way

These updates exemplify Arch Linux's core principles:

1. Simplicity

Arch doesn't add patches or modifications. You get vanilla upstream software, which means:

• Bugs can be reported directly upstream
• Documentation from upstream applies directly
• No distribution-specific quirks to learn

2. Modernity

Rolling release means you always have the latest:

• Kernel 6.9 available as soon as it's stable
• GNOME 47 the day it's released
• Security patches within hours, not days or weeks

3. Pragmatism

Arch makes practical decisions:

• systemd as init (most tested, most features)
• Binary packages (fast installation, unlike Gentoo)
• Official + AUR (best of both worlds for software availability)

4. User Centrality

Arch targets competent users who want control:

• Manual installation teaches system architecture
• Minimal base system, you add only what you need
• No handholding, but excellent documentation (ArchWiki)

5. Versatility

Build any system you want:

• No pre-configured desktop environment (you choose)
• Can be minimal server or full-featured workstation
• Suitable for containers, embedded systems, desktops

How to Update Your Arch System

Standard Update

# Update package database and upgrade all packages
sudo pacman -Syu

# If you see keyring errors, update keyring first
sudo pacman -S archlinux-keyring && sudo pacman -Syu

Major Updates Requiring Intervention

Some January updates required manual steps:

1. systemd 256 Requires Configuration Review

# Find new configuration files
sudo find /etc -name '*.pacnew'

# Use pacdiff to merge changes (requires pacman-contrib)
sudo pacdiff

2. Kernel 6.9 May Break Proprietary NVIDIA

If using NVIDIA proprietary drivers:

# Update nvidia packages
sudo pacman -S nvidia nvidia-utils

# If using LTS kernel
sudo pacman -S nvidia-lts

# Rebuild initramfs
sudo mkinitcpio -P

Clean Package Cache

Free up disk space by removing old packages:

# Remove all cached versions of uninstalled packages
sudo pacman -Sc

# Remove all cached packages (use with caution)
sudo pacman -Scc

# Keep only 2 most recent versions (requires paccache)
sudo paccache -rk2

AUR Updates

If you use the Arch User Repository (AUR), update those packages separately:

# Update both official and AUR packages
yay -Syu

# Only update AUR packages
yay -Sua
