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
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
