# Alfred Linux

**AI-Native Operating System — Kernel 7.0 · 32 Security Modules · Zero Telemetry**

Alfred Linux is a Debian-based operating system where security, privacy, and AI are architectural decisions — not aftermarket add-ons. Custom-compiled kernel 7.0, 32 hardened security modules active from first boot, AI IDE and voice assistant preinstalled, zero telemetry by architecture.

Built by [GoSiteMe Inc.](https://gositeme.com) — not a weekend fork, not a reskin with a wallpaper change.

**Total: 2,527 lines of build code across 10 hooks + build scripts.**

This is not a config tweak. This is a build system.

## How the Build Works

```bash
# Requires: Debian 12+ host, live-build, root/sudo
cd scripts/
sudo ./build-unified.sh
```

`build-unified.sh` is the orchestrator. It:
1. Configures live-build for Debian Trixie (13) with XFCE
2. Drops all 10 hooks into the chroot build pipeline
3. Each hook runs in order (0100 → 0600) inside the chroot
4. Hooks install packages, write configs, enable services, apply hardening
5. Two kernel-naming hooks (9999) fix the UEFI/BIOS boot path
6. live-build produces the hybrid ISO (UEFI + BIOS bootable)

### The Critical Boot Fix (RC2→RC3)

Bootloader references `/live/vmlinuz` but live-build only creates versioned files (`vmlinuz-6.1.0-44-amd64`). Two hooks fix this:
- **Chroot hook (9999):** Creates generic kernel copies in `/boot/`
- **Binary hook (9999):** Creates generic copies in `binary/live/` after lb copies versioned files

Without both, the ISO boots to a kernel panic. This is the kind of real-world debugging that separates build systems from config generators.

## Security Architecture (570 lines, hook 0160)

The security hook alone is 570 lines. It doesn't just install packages — it installs and **configures** 32 modules:

- **Mandatory Access Control:** AppArmor enforced, custom profiles loaded
- **Intrusion Detection:** fail2ban with SSH/HTTP jails, auditd with CIS-aligned rules
- **File Integrity:** AIDE baseline database initialized at build time
- **Antivirus:** ClamAV with freshclam cron, rkhunter, chkrootkit
- **Firewall:** nftables with drop-by-default policy (not UFW — raw nftables)
- **Encryption:** LUKS2 full disk encryption via Calamares option
- **Network:** MAC address randomization (WiFi + Ethernet), DNS-over-TLS, sysctl hardening
- **Kernel:** 24 CPU mitigations including 3 kernel-7-exclusive (ITS, TSA, VMSCAPE)
- **Sysctl:** CIS Level 2 hardening — ICMP redirects disabled, SYN cookies enabled, IP forwarding off, core dumps disabled

For comparison: Ubuntu ships with UFW installed but **off**. Fedora ships with SELinux that users routinely **disable**. Arch ships with **nothing**.

## Build Server

ISOs are built on a dedicated EU build server:
- 8 cores, 32 GB RAM
- Debian Bookworm host (migrating to Trixie)
- Isolated build environment (clean chroot each run)

## Verification

```bash
# Download
wget https://alfredlinux.com/downloads/alfred-linux-4.0-rc8-amd64.iso

# Verify hash
sha256sum alfred-linux-4.0-rc8-amd64.iso

# Boot in QEMU (no install required)
qemu-system-x86_64 -m 4096 -cdrom alfred-linux-4.0-rc8-amd64.iso -boot d

# Once booted, verify:
uname -r                    # → 7.0.0-rc7-alfred
alfred-security-status      # → 32 modules active
alfred-network-status       # → nftables + MAC randomization
systemctl status fail2ban   # → active (running)
systemctl status apparmor   # → active (running)
```

## Progress — Turning Weaknesses Into Wins

| What We Admitted | What We Shipped |
| --- | --- |
| No community infrastructure | [Community hub](https://alfredlinux.com/community) with contribution workflows, all 8 repos public on [GoForge](https://alfredlinux.com/forge/explore/repos) |
| No hardware testing matrix | [Hardware Compatibility List](https://alfredlinux.com/hardware) — VMs, bare metal, mobile, known limitations |
| No LTS cadence | [Roadmap](https://alfredlinux.com/roadmap) with timeline, GA goals, and LTS planning tracked in [GoForge issues](https://alfredlinux.com/forge/commander/alfred-linux/issues) |
| Not on DistroWatch | Submitted — waiting list |
| No contribution guide | [CONTRIBUTING.md](CONTRIBUTING.md) — bug reports, code workflow, hardware test submissions, security reporting |

We'd rather ship 32 hardened security modules with zero community than ship zero security modules with a million users.
