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>

# fix-limine-uki-entry.sh — idempotent. REQUIRES ROOT.
|
|
#
|
|
# With ENABLE_UKI=yes, limine removes /boot/vmlinuz-linux and
|
|
# /boot/initramfs-linux.img (UKI-only), but the installer-seeded first entry
|
|
# "/NoSignal (Arch Linux)" in limine.conf still uses `protocol: linux` ->
|
|
# boot():/vmlinuz-linux. That entry is the default auto-boot target and now
|
|
# dead-boots to a TTY. This converts it to a `protocol: efi` entry that boots
|
|
# the UKI, keeping the same label (so it stays first = default) and cmdline.
|
|
#
|
|
# Idempotent: if the entry is already protocol:efi (no vmlinuz path), it's a
|
|
# no-op. Always backs up limine.conf first. Refuses if the UKI is missing.
|
|
#
|
|
# NOTE: the durable fix belongs in the ISO installer's seeded limine.conf /
|
|
# limine config — see README. This repairs an already-installed system.
