veilor-os

Hardened minimal Fedora KDE remix. Black-on-black. Locked down by default.

veilor-os is a Fedora 43 KDE spin built for operators who want a clean, fast, opinionated desktop with serious hardening already in place. No prompts at install beyond the LUKS passphrase. Boot, set admin password, work.

Highlights

• Single-prompt install — only LUKS passphrase. No account wizard, no initial-setup screen. admin account is created automatically; password is set on first boot.
• Hardened by default — SELinux enforcing, USBGuard, fail2ban, firewalld drop zone, kernel sysctl lockdown, NTS-authenticated NTP, DNS-over-TLS.
• 3-mode power management — veilor-power save | mid | perf, with AC/battery auto-switching via udev. Backed by tuned profiles.
• Fira Code system font — programming ligatures, monospace consistency across UI + terminal. (DuckSans planned for v0.3.)
• Pure-black KDE color scheme — veilor-black theme system-wide.
• LUKS2 + Secure Boot — argon2id, aes-xts, btrfs subvolumes, zram swap (no disk swap, no cold-boot leak).
• Reproducible build — kickstart + podman + livemedia-creator. ISO output is deterministic given pinned base.
