# Debianito - Post-Installation Automation for Debian

<div align="center">

Debianito is a user-friendly post-installation automation script for Debian 11 (Bullseye), Debian 12 (Bookworm) and Debian 13 (Trixie). It streamlines system configuration, driver installation (including NVIDIA drivers with legacy support via rescue environment), repository setup with backports support, gaming tools integration, and more with an interactive menu-driven interface.

## User Privileges & Feedback

Admin rights, passwordless commands, and file ownership fixes—optimized for Debian users.

### 1. Sudo Group Membership
If you just installed Debian and can’t install software or change system settings (you get "Permission denied"), this option adds your user to the sudo group. This gives you admin privileges so you can manage your system. Changes take effect after you log out and back in.

### 2. Passwordless Sudo for Frequent Tasks
Every time you run sudo apt install or sudo reboot, Linux asks for your password. This option lets you skip typing your password for common commands like installing/updating software (apt), restarting or shutting down (systemctl).
- ⚠️ Security Note: While convenient, this reduces security if someone else uses your PC physically.

### 3. Repair Home Directory Ownership
Sometimes, when you use sudo incorrectly (e.g., installing games or apps), files get "stolen" by the system (root) instead of your user. This causes apps to fail (e.g., saving settings or game progress). This option fixes ownership so all your files and folders belong to you again.

### 4. Sudo Password Feedback (Asterisks)
By default, Debian’s terminal hides your password (no asterisks or feedback). This option adds visual feedback (e.g., ****) so you can see how many characters you’ve typed. Toggle it on/off as needed.
