From 91e1d32f1c6e0973ef50b29aae983871a476dd7b Mon Sep 17 00:00:00 2001 From: Michael Smith Date: Fri, 20 Feb 2026 17:06:46 +0100 Subject: [PATCH] Make preseed fully unattended with Hyprland desktop from sid Overhaul preseed.cfg from a semi-interactive installer (prompting for LUKS passphrase and user credentials) to a fully unattended dev/test setup with hardcoded credentials. Enable networking and configure a Debian sid pin to pull Hyprland, UWSM, SDDM, and foot during late_command. Add serial console support in GRUB for headless debugging. Also update the FSD with the "match upstream Omarchy" design principle and bump the last-updated date.
