YALI (Yet Another Linux Installer) — Rust / egui

A rewritten Pisi GNU/Linux installation tool in Rust and egui. YALI installs the system from the live environment, installs packages, and performs basic configuration. It is a modern, fast, and maintainable rewrite of the original Python/Qt version.

Features

• 10-step installation wizard: Welcome → Location → Keyboard → Network → Disk Partitioning → Users → Bootloader → Summary → Installation → Finish
• Squashfs-based: the installed system is copied from the ISO's squashfs, packages are not fetched over the network. The display manager, desktop environment and packages come from the ISO, so the wizard does not offer them (offering them would be misleading, since the copy would overwrite the choice)
• Two modes: Graphical interface (default) and automatic installation with answer file (--auto-install answer.toml)
• Demo mode: Skips system checks, simulates installation (--demo)
• Disk partitioning: Automatic (GPT/MBR) or manual, LVM and LUKS encryption support
• Network configuration: WiFi scanning (nmcli), proxy settings
• Bootloader: GRUB device/password/timeout settings, kernel parameters
• Rescue mode: Chroot, GRUB reinstallation, Pisi rollback
• OEM mode: Predefined settings for manufacturer pre-installation
• Internationalization: Turkish and English (with rust-i18n via TOML locale files)
• Branding system: Runtime-loadable branding.toml for logo, slides, color settings
• Theme: Dark/light theme, atomic color management, custom gradient buttons
• Async job queue: All installation steps run in separate tokio runtime, UI updated via mpsc channel
• System checks: 8 pre-checks including RAM, disk space, internet, UEFI, CPU, NVMe
• Slideshow: Custom branded slides for 9 desktop environments
• Demo session cleanup: Removes live environment artifacts, adds production repository

Usage

# Normal installation (requires root)
sudo cargo run --release

# Demo mode (no root required)
cargo run --release -- --demo

# Automatic installation (with answer file)
sudo cargo run --release -- --auto-install answer.toml

# Slideshow test (standalone window, no root required)
cargo run --bin slides_test [desktop] [lang]
# E.g.: cargo run --bin slides_test xfce en

Installation Workflow

1. Welcome — Language selection, system checks, rescue mode
2. Location / Time — Timezone selection (region/area dual ComboBox), GeoIP, NTP or manual date/time
3. Keyboard — Layout/variant selection, search, live preview (setxkbmap)
4. Network — WiFi scanning, connection, proxy
5. Disk Partitioning — Automatic (guided) or manual, LVM, LUKS
6. Users — Account creation, password strength indicator, root password, autologin
7. Bootloader — GRUB device, timeout, password, kernel parameters
8. Summary — Review all selections
9. Installation — Slideshow + progress bar + live log
10. Finish — Successful installation, reboot or return to live desktop
