Append a v0.5.32 entry documenting that ISO builds moved from GitHub Actions to the Forgejo runner on nullstone, that the hybrid VM test procedure is unchanged, that the ISO is now pulled from the ci-latest Forgejo release tag, and that virtio-9p host log capture is on by default (replaces the broken virtio-serial path flagged by Agent 6 in the 2026-05-05 wave). TESTING.md itself is intentionally untouched — only the build host and download URL changed; the procedure prose still applies as-is. |

veilor-os
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'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 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.
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): Plymouth
- SDDM polish, signed ISOs (own MOK + GPG, sigstore/cosign on OCI),
AppArmor + nftables stack,
veilor-update/veilor-doctor/veilor-postinstallhelpers, public docs site, bootc OCI hybrid spike at v0.7, bootc-only at v1.0.
Quick install
# 1. Download the ISO (after public release; CI artifact for now)
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 rootreportsL. There is nosu -to root, ever. Usesudo. - No PackageKit, no Flatpak by default. Updates happen with
sudo dnf upgradeon your terms, not in the background. - Default firewall zone is
drop, notFedoraWorkstation. 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 | perfswaps 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 tosavewhen 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.
