SparkOS Root Filesystem
=======================
This is the root filesystem for SparkOS, a minimal Linux distribution.
This is the root filesystem for SparkOS, a GUI-only Linux distribution.
Minimal System Packages:
- Linux Kernel (with networking support)
- SparkOS Init System (custom)
- Busybox (shell, utilities, networking)
- Git (for installing spark CLI)
- Sudo (privilege elevation)
SparkOS Philosophy:
- GUI-Only: No CLI tools, no shell, no Unix utilities
- Network-First: Networking integrated into Qt6 GUI
- Direct Kernel Interface: Qt6 communicates directly with Linux kernel
- No Unix Baggage: No users, groups, passwords, or authentication
Minimal System:
- Linux Kernel (with networking and framebuffer support)
- SparkOS Init System (completely self-contained, no dependencies)
- Qt6 GUI Application (all user interaction)
Directory Structure:
/bin, /sbin - Essential binaries
/etc - Configuration files
/sbin - Init binary only
/etc - Minimal configuration files
/proc, /sys, /dev - Kernel interfaces
/tmp - Temporary files
/usr - User programs
/var - Variable data
/usr - Qt6 GUI application and libraries
/var - Variable data (overlay mount)
/root - Root home directory
/home/spark - Default user home directory
Default User:
Username: spark (UID 1000)
Home: /home/spark
Sudo: Full access without password
Scripts: ~/clone-sparkos.sh for installing spark CLI
Network Configuration:
/etc/network/interfaces - Wired network (DHCP)
/etc/resolv.conf - DNS configuration (8.8.8.8, 1.1.1.1)
/sbin/init-network - Network initialization script
- Managed entirely through Qt6 GUI
- Init brings up interfaces via direct ioctl calls
- DHCP and network management handled by Qt6 NetworkManager
- /etc/resolv.conf provides fallback DNS servers
Bootstrap Process:
1. System boots as 'spark' user with wired networking (DHCP)
2. Run ~/clone-sparkos.sh to install spark CLI
3. Use spark CLI to configure WiFi and system
4. Install additional packages via spark CLI
5. Use 'sudo' for any root-level operations
Boot Process:
1. Linux kernel loads
2. Init (PID 1) mounts filesystems
3. Init brings up network interfaces
4. Init spawns Qt6 GUI application
5. All user interaction through GUI
Note: This is a minimal system. You'll need to populate /bin and /usr/bin
with actual binaries (busybox, git, sudo) from a proper Linux system
or by cross-compiling.
Note: This is a minimal, GUI-only system.
No shell, no CLI tools, no busybox.
All functionality is provided through the Qt6 GUI application.
