- Fixed script crashes from `whiptail` Cancel/Esc under `set -e`. Added `_menu()`, `_checklist()` and `_inputbox()` wrappers with `|| true` to prevent premature exits.
- Resolved startup failures by using defaults instead of relying on unset variables with `set -u`.
- Hardened sudoers management — `_validate_sudoers()` writes to temp file, validates with `visudo -cf`, only copies if successful.
- Replaced `eval` in `_run_cmd` with safer `bash -c` execution.
Swap Management Module (`modules/swap.sh`)
- New standalone module with 9 internal functions and `manage_swap()` entry point.
- Btrfs CoW detection — applies `chattr +C` before swapfile creation to prevent mkswap rejection on Btrfs.
- Dynamic swappiness configuration — reads current system value instead of hardcoding 60, pre-fills inputbox with existing setting.
- Uses `/run/lock/debianito-swap.lock` for early init compatibility (added as option 9 in main menu).
Repository & Branch Migration (`modules/repos/migrate.sh`)
- Handles branch migration from stable (11/12) to Testing or SID with 5-screen UX flow.
- Persistent backup system — creates timestamped tar.gz backups of `/etc/apt/sources.list*`, auto-restores on apt update failure.
- SID guardrails — installs `apt-listbugs` and `apt-listchanges` before upgrade to warn about critical bugs in unstable packages.
- Dynamic menu options based on Debian version (SID shows only 1-2-3 Exit, non-SID includes backports + branch migration).
- New `_components_enabled()` helper detects current contrib/non-free state.
Gaming Module Overhaul
- Unified gaming checklist — merged i386 toggle into single prompt with lazy evaluation instead of separate pre-check.
- Lazy 32-bit architecture enablement — only enables i386 when needed (steam/lutris/i386 selected) and installs graphics drivers if `need_32bit=true`.
- New `_install_nvidia_32bit()` helper with proper driver detection, version pinning, and legacy/tesla variant handling.
Heroic & OpenRGB Downloads
- Heroic — fetches latest release from GitHub API using `jq` to extract amd64.deb URL, validates with `dpkg-deb --info`.
- OpenRGB — downloads from Codeberg Gitea API with SHA256 verification when available, fallback to `dpkg-deb` validation.
- Dynamic codename detection — now detects Bookworm vs Trixie at runtime instead of hardcoded static values for .deb download URLs.
|Other Improvements
- Renumbered main menu: 8=ZRAM, 9=Swap Management, 10=Extras, 11=Boot Rescue, 12=Exit.
- Improved `detect_storage()` — excludes loop/CD-ROM devices via `lsblk -e 7,11`, explicitly skips zram, detects USB/SD via `/sys/block/$name/removable`.
- Standardized SCROLL_HINT across all files with centralized readonly variable.
- System Time (NTP)*: Overhauled `modules/utils.sh`. `check_system_time()` now warns if year < 2025 and enables NTP silently if off but valid. `sync_system_time()` conditionally installs/starts `systemd-timesyncd` and verifies synchronization via `timedatectl NTPSynchronized`.
- LightDM Configuration: Added `_configure_lightdm()` to ensure the user list is visible in the greeter. Installs `lightdm-gtk-greeter-settings` and creates an override config (`99-show-users.conf`) during startup without interrupting the flow.
- Wine Installation: Simplified Wine setup in `system.sh` and Bullseye `extras.sh`. Removed i386 multiarch logic; now installs only `wine64 fonts-wine`. Added post-install version verification to confirm successful deployment.
- Lutris Dependencies: Updated `install_lutris()` in `tools.sh` and `legacy.sh`. Now conditionally adds `wine32` only if the system supports i386 architectures, preventing dependency failures on 64-bit-only setups.
- Boot Rescue Module: Created new standalone `modules/rescue.sh`. Provides UEFI boot repair tools: Secure Boot refirm (shim + GRUB) and Initramfs regeneration for all kernels. Integrated into the main menu as a dedicated rescue section.
