From arch-knowledge-patch
Provides Arch Linux breaking changes since mid-2024: pacman 7.0 alpm user, Valkey replacing Redis, Plasma 6.4 Wayland-only, NVIDIA 590 open modules, Dovecot 2.4, linux-firmware split. Load for Arch tasks.

/arch-knowledge-patch:arch-knowledge-patchThe summary Claude sees in its skill listing — used to decide when to auto-load this skill
Claude's baseline knowledge covers Arch Linux through mid-2024, pacman 6.x. This skill provides breaking changes and major package transitions from late 2024 onwards.
Provides CentOS Stream 10 updates post-training cutoff: x86_64_v3 minimum, Wayland-only (Xorg removed), Valkey replaces Redis, modularity/desktop apps removed. Load before CentOS Stream work.
Patches Claude's knowledge with Ubuntu 25.10+ changes: sudo-rs replacing GNU sudo, rust-coreutils, APT 3.1 solver, OpenSSH 10.0, OpenSSL 3.5, Chrony NTS, Wayland-only GNOME. Load for recent Ubuntu tasks.
Provides Rocky Linux 10+ updates: DNF 5 modularity removal, Valkey replacing Redis, rpmsort for RPM sorting, rh_waived kernel arg. Use for package management and service migrations post-9.x.

| Date | Change | Impact | Details |
|---|---|---|---|
| 2024-09 | pacman 7.0 — alpm user | Downloads run unprivileged; local repos need chown :alpm | pacman-7 |
| 2025-04 | Redis → Valkey | redis removed from [extra]; use valkey-cli, valkey.service | server-packages |
| 2025-06 | Wine WoW64 build | Multilib no longer needed; existing 32-bit prefixes must be recreated | desktop-graphics |
| 2025-06 | Plasma 6.4 Wayland-only | X11 session removed by default; install plasma-x11-session first | desktop-graphics |
| 2025-06 | linux-firmware split | Vendor packages; NVIDIA symlink conflict requires pacman -Rdd workaround | desktop-graphics |
| 2025-08 | Zabbix unified user | Per-component users removed; all run as zabbix | server-packages |
| 2025-10 | Dovecot 2.4 | Configs incompatible with 2.3; service won't start until migrated | server-packages |
| 2025-12 | .NET 10.0 default | Unversioned packages jump to 10.0; install dotnet-sdk-9.0 to keep 9.0 | server-packages |
| 2025-12 | NVIDIA 590 open modules | Pascal (GTX 10xx) and older dropped; use nvidia-580xx-dkms from AUR | desktop-graphics |
pacman 7.0 introduced privilege-separated downloads via a dedicated alpm system user. Packages are no longer downloaded as root.
Fix local repo access after upgrading:
chown :alpm -R /path/to/local/repo
# Ensure +x on directories so alpm user can traverse
After upgrading, merge .pacnew files (/etc/pacman.conf, /etc/makepkg.conf) to pick up new defaults.
Git source checksums may change for repos using .gitattributes — one-time PKGBUILD checksum update may be needed.
See references/pacman-7.md for details.
Redis was dropped from [extra] due to its license change (BSD-3-Clause to RSALv2/SSPLv1). Valkey is the BSD-licensed, API-compatible drop-in replacement.
| Old | New |
|---|---|
redis | valkey |
redis-cli | valkey-cli |
redis-server | valkey-server |
redis.service | valkey.service |
pacman -S valkey
systemctl enable --now valkey.service
The old redis package is in the AUR only. Update all scripts and configs referencing old names.
wine and wine-staging switched to a pure WoW64 build. The multilib repository is no longer needed for Wine.
Breaking: Existing 32-bit Wine prefixes must be recreated:
rm -rf ~/.wine
# Then reinstall your applications
Known limitation: 32-bit apps using OpenGL directly may have reduced performance under WoW64 mode.
Plasma 6.4 split kwin into kwin-wayland and kwin-x11. Only Wayland is installed by default. X11 users who don't act will lose their login session.
# Install BEFORE upgrading to Plasma 6.4:
pacman -S plasma-x11-session
linux-firmware was split into vendor packages (linux-firmware-nvidia, linux-firmware-intel, etc.). The meta-package depends on a default set of these.
Breaking: Upgrading from 20250508 or earlier fails due to NVIDIA firmware symlink conflicts:
pacman -Rdd linux-firmware
pacman -Syu linux-firmware
Per-component users (zabbix-server, zabbix-proxy, zabbix-agent, zabbix-web-service) are removed. All components now run as a single zabbix user from zabbix-common.
Main configs and systemd units migrate automatically. Manual fix needed for custom files:
chown zabbix:zabbix /etc/zabbix/zabbix_agentd.psk
# Update sudoers: "zabbix-agent ALL=..." → "zabbix ALL=..."
After migrating, remove obsolete accounts (userdel zabbix-server, etc.).
Dovecot 2.4 configs are incompatible with 2.3. The service will not start until migrated. The replication feature was removed.
Legacy fallback packages in [extra]:
pacman -S dovecot23 pigeonhole23
# Also: dovecot23-fts-elastic, dovecot23-fts-xapian
Unversioned packages (dotnet-sdk, dotnet-runtime, aspnet-runtime) jumped to .NET 10.0. pacman may fail with dependency errors during upgrade.
Keep 9.0 alongside 10.0:
pacman -Syu aspnet-runtime-9.0
pacman -Rs aspnet-runtime
# Same pattern for dotnet-sdk-9.0, dotnet-runtime-9.0
Package mapping:
| Old | New |
|---|---|
nvidia | nvidia-open |
nvidia-dkms | nvidia-open-dkms |
nvidia-lts | nvidia-lts-open |
Turing (RTX 20xx / GTX 1650) and newer transition automatically on upgrade.
Breaking for Pascal (GTX 10xx) and older — the 590 driver drops support entirely. Upgrading will break your graphical environment:
pacman -R nvidia # or nvidia-dkms / nvidia-lts
yay -S nvidia-580xx-dkms
