The Foundation

The world runs on these three. So do we.

GNU

The userspace that makes Linux livable. The GPL that keeps it free.

gnu.org

Linux

The kernel. The foundation. Everything runs on it.

kernel.org

Debian

30+ years. Universal. Stable. Free.

debian.org

Survivors

Still here. Still irreplaceable.

GentooCompiles for anything. The deepest way to learn Linux.Alpinemusl. 5MB. Container standard.TailsAmnesic. RAM-only. Zero trace.OpenBSDPledge, unveil, pf. The most audited codebase on earth. Never compromised.
Available via Tebian Menu → Virtualization & dual boot
macOSThe only way to run Xcode. Proprietary, but worth keeping close.WindowsAnti-cheat games. Proprietary software. Still the only option sometimes.

Server Management

Manage what runs, what stores, and what ships.

ProxmoxBare-metal Type-1 hypervisor. VMs, LXC, clustering, HA.TrueNASZFS storage OS. Now also runs Docker apps. The sovereign homelab foundation.TeployApp deployments made easy. SSH-native CLI with a live state dashboard — ship code and see your fleet.

Embedded & Real-Time

Not Linux. Not general purpose. Built for one job, perfectly.

ZephyrLinux Foundation RTOS. The modern embedded standard.FreeRTOSThe microcontroller OS. Runs on everything from Arduino to AWS IoT.seL4Formally verified microkernel. Mathematically proven correct.RTEMSReal-time OS. Used in space missions and safety-critical systems.

The Killed

Distros we replaced. And why they died.

UbuntuDebian + Snap + Canonical. We skip the middleman.
ArchRolling = breaking. Stability wins. AUR via Distrobox.
Fedora6-month forced upgrades. Corporate backing. No thanks.
Enterprise LinuxRHEL, Rocky, Alma — sell liability, not technology.
MintUbuntu + theme. We go straight to Debian.
Pop!_OSGaming stack + GNOME. Install via Tebian Menu instead.
ManjaroArch with training wheels. Still breaks.
EndeavourOSArch installer with a GUI. Still Arch underneath.
FreeBSDZFS, DTrace, jails — Linux absorbed them all. Even TrueNAS moved on.
KaliJust tools. apt install nmap metasploit. Done.
ParrotKali with a theme. Same tools, more bloat.
NixOSGit is your reproducibility. Declarative config is a full-time job. Not FHS compliant.
GuixSame idea as Nix but in Lisp. Twice as academic, half as useful.
openSUSEYaST, Zypper, BTRFS by default. Different for different's sake.
Voidmusl + minimal? That's Alpine. runit is cool, not enough.
SolusIndependent distro. Tiny team. Uncertain future.
ZorinUbuntu + Windows theme. We don't pretend.
elementaryUbuntu + macOS theme. Same trick, different skin.
MX LinuxDebian + XFCE + tools. Just use Debian.
antiXMX without systemd. We respect the cause, not the result.
DeepinPretty DE. Chinese telemetry concerns. Pass.
QubesFor one-off anonymity, use Tails. For a hardened daily driver, harden Debian.
WhonixTwo-VM Tor overhead. Tails does it cleaner.
Tiny CoreAlpine is 5MB and actually usable. This is a curiosity.
PuppyRAM-based. Old hardware. Old everything.
TempleOSNot Linux. God's temple. Rest in peace, Terry. The temple still stands somewhere in Tebian.
