GitHub mirror was disabled 2026-05-06; the GH Actions badge would now 404 on every render. Swap it for the Forgejo workflow badge, add a short "primary git host" note in Status pointing at git.s8n.ru, and update the Quick install snippet so the ISO download URL points at the Forgejo `ci-latest` rolling release tag instead of "CI artifact for now". No technical detail moves out of SYSTEM/STRATEGY here — just keep the top-of-readme accurate now that GH is dead.

> **Hardened minimal Fedora KDE spin. Black-on-black. Locked down by default.**

|
veilor-os is a Fedora 43 KDE Plasma remix for operators who want a clean,
|
|
fast, opinionated desktop with serious hardening already wired in. Boot the
|
|
ISO, set an admin password, work. No installer wizard. No initial-setup
|
|
screen. No telemetry. No "would you like to enable X" prompts.
|
|
|
|
The current install path is an Anaconda kickstart with a custom gum TUI
|
|
on top. v0.7+ ships a hybrid path: the kickstart ISO becomes the bootstrap
|
|
installer (Anaconda's LUKS UX is mature), but the root filesystem is
|
|
populated directly from a cosign-signed bootc OCI image built via BlueBuild
|
|
on top of [secureblue](https://github.com/secureblue/secureblue)'s
|
|
hardened Kinoite variant. Updates from there flow through `bootc upgrade`
|
|
— atomic A/B, instant rollback. v1.0 is bootc-only.
|
|
|
|
See [docs/STRATEGY.md](docs/STRATEGY.md) for the full trajectory.

|
|
## Status
|
|
|
|
Active development on the install path. Three bug classes have been
|
|
worked through (LUKS unlock cmdline, anaconda RPM-6.0 cmdline-mode
|
|
brittleness, bootloader install via `gen_grub_cfgstub`); current focus
|
|
is the v0.5.32 blocker list from the
|
|
[2026-05-05 9-agent research wave](docs/research/2026-05-05-agent-wave/README.md).
|
|
|
|
Primary git host: <https://git.s8n.ru/veilor-org/veilor-os>. The GitHub
|
|
mirror was disabled 2026-05-06; this repo is private-by-default on
|
|
Forgejo. ISO builds and CI artifacts are produced by the Forgejo runner
|
|
on nullstone — no GitHub Actions involvement.
|
|
|
|
What is **shipping**: hardening (SELinux, sysctl, USBGuard, fail2ban,
|
|
firewalld), KDE black theme, Fira Code system font, 3-mode power
|
|
management, single-prompt LUKS install, first-boot admin password flow,
|
|
reproducible CI build, EFI+BIOS bootable live ISO.
|
|
|
|
What is **planned** (see [docs/ROADMAP.md](docs/ROADMAP.md)): Plymouth
|
|
+ SDDM polish, signed ISOs (own MOK + GPG, sigstore/cosign on OCI),
|
|
AppArmor + nftables stack, `veilor-update` / `veilor-doctor` /
|
|
`veilor-postinstall` helpers, public docs site, **bootc OCI hybrid
|
|
spike at v0.7**, **bootc-only at v1.0**.

|
|
## Quick install
|
|
|
|
```bash
|
|
# 1. Download the ISO from the latest Forgejo release.
|
|
# https://git.s8n.ru/veilor-org/veilor-os/releases/tag/ci-latest
|
|
# (rolling tag; replaced on each successful build-iso.yml run)
|
|
sha256sum -c veilor-os-43-*.iso.sha256
|
|
|
|
# 2. Flash to USB. Replace /dev/sdX with your USB device — triple-check.
|
|
sudo dd if=veilor-os-43-*.iso of=/dev/sdX bs=4M status=progress conv=fsync
|
|
sync
|
|
|
|
# 3. Boot from USB, pick "Install veilor-os" from the menu.
|
|
# 4. Set a strong LUKS passphrase — the only prompt during install.
|
|
# 5. Reboot, remove USB.
|
|
# 6. On first boot: TTY prompts for an admin password (≥14 chars, mixed case,
|
|
# digit, symbol). Once accepted, SDDM starts. Log in as `admin`.
|
|
```

## What veilor-os ships
|
|
|
|
| Layer | Hardening |
|
|
|-------|-----------|
|
|
| Boot | Secure Boot, `lockdown=integrity`, `slab_nomerge`, `randomize_kstack_offset=on`, `vsyscall=none`. LUKS2 (aes-xts-plain64, argon2id, mem=1GB). zram swap (no disk swap, no cold-boot leak). |
|
|
| Kernel | Locked sysctls: ptrace=2, kptr_restrict=2, dmesg_restrict=1, perf_event_paranoid=3, BPF JIT hardening, full ASLR, no SUID core dumps. |
|
|
| MAC | SELinux **enforcing**, targeted policy + custom `veilor-systemd` module. |
|
|
| Network | firewalld zone = `drop`, ssh only inbound. systemd-resolved with DNS-over-TLS (Cloudflare/Quad9 fallback), LLMNR off. NTS-authenticated chrony time. |
|
|
| SSH | password auth off, root login off, single `admin` user, X11 forwarding off, MaxAuthTries 3. |
|
|
| Auth | root **locked**, single `admin` user with sudo. pwquality minlen=14, 4 character classes. First-boot password forced via `chage -d 0`. |
|
|
| Audit | `auditd` rules covering passwd/shadow/sudoers/ssh/cron/sysctl/kernel modules and all privileged binaries. |
|
|
| IDS | `fail2ban` with sshd + pam-generic jails, journal backend, firewalld rich-rule action. |
|
|
| USB | `USBGuard` daemon, **default-block**, empty allowlist on first boot. |
|
|
| Services off | `abrt*`, `cups`, `geoclue`, `avahi-daemon`, `bluetooth`, `ModemManager`, `gssproxy`, `atd`, `pcscd`, `kdeconnectd`, `PackageKit`. |
|
|
| UX | KDE Plasma minimal, `BreezeBlackPure` colour scheme, Fira Code system font, `veilor-power save \| mid \| perf` with udev AC/battery auto-switch. |

## 60-second tour — what's different from stock Fedora KDE
|
|
|
|
- **No Anaconda Initial Setup** wizard after first boot. Single LUKS
|
|
passphrase prompt is the entire install interaction. Admin user is
|
|
pre-created; password is set once on TTY1, then SDDM starts.
|
|
- **Root is locked.** `passwd -S root` reports `L`. There is no `su -`
|
|
to root, ever. Use `sudo`.
|
|
- **No PackageKit, no Flatpak by default.** Updates happen with
|
|
`sudo dnf upgrade` on your terms, not in the background.
|
|
- **Default firewall zone is `drop`**, not `FedoraWorkstation`. The only
|
|
thing your machine answers is sshd on its assigned port.
|
|
- **USBGuard blocks every USB device by default.** First-boot procedure:
|
|
plug in everything you trust, run `usbguard generate-policy`,
|
|
done.
|
|
- **Black-on-black KDE.** Wallpaper, panel, Konsole all match. No "white
|
|
flash" anywhere in the session.
|
|
- **`veilor-power save | mid | perf`** swaps the full tuned profile,
|
|
CPU governor, EPP, battery threshold, and screen-dim policy in one
|
|
command. Wired to AC/battery udev events too — laptop drops to `save`
|
|
when unplugged automatically.

|
|
|
veilor-os is **not** trying to compete with Whonix-style anonymity or
|
|
Qubes-style isolation. It is a **hardened daily-driver desktop** — fast,
|
|
clean, locked down, with no manual post-install hardening required.
