Single-script builder (nosignal.sh) that turns a stock Arch Linux ISO into a fully-offline installer for a themed Hyprland + caelestia (Quickshell) desktop: matching SDDM greeter, Btrfs/Limine bootable snapshots, chwd-style GPU detection, and a curated "os updates" layer (keybind cheatsheet, settings panels, system polish, on-box management skill). See README.md. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# nosignal-cachy-db-clean — repair tool for boxes already contaminated by a
|
|
# CachyOS pacman run.
|
|
#
|
|
# Symptom this fixes: every pacman/yay op prints a flood of
|
|
# warning: <pkg>: unknown key '%INSTALLED_DB%' in local database
|
|
# `%INSTALLED_DB%` is a field the CachyOS `pacman` build writes into the local DB;
|
|
# stock Arch pacman doesn't understand it and warns about it on EVERY operation.
|
|
# It is harmless (the DB is structurally valid — `pacman -Dk` passes — and
|
|
# transactions resolve fine), but it looks exactly like database corruption.
|
|
#
|
|
# This strips the `%INSTALLED_DB%` field from every /var/lib/pacman/local/*/desc.
|
|
# Each block is exactly: a `%INSTALLED_DB%` line + one value line + a blank
|
|
# separator. Idempotent — only rewrites files that contain the field; safe to
|
|
# re-run. Use --dry-run to preview. REQUIRES ROOT (writes the local DB) unless
|
|
# --dry-run.
