Download .tar.gz (~9 KB) Requires a Debian/Ubuntu Linux box + a fleet account

🐧 Linux USB Creator — install steps

  1. Download freezeos-usb-creator.tar.gz above.
  2. Extract it: tar -xzf freezeos-usb-creator.tar.gz
  3. Enter the folder: cd freezeos-usb-creator
  4. Run it: ./freezeos-usb-creator
    On first launch it installs everything it needs (GTK, gdisk, dosfstools, parted, curl, polkit) via apt — it will ask for your sudo password.
  5. In the app: Log in with your fleet account, pick your device (for its performance kernel) or Generic, choose a channel, optionally enter WiFi, select the target USB drive, then Create USB.
  6. Use Update installer anytime to pull the latest FreezeOS installer image.
  7. Eject the USB and boot the target machine from it — it auto-joins WiFi, enrolls under your account, and installs FreezeOS.

⚠ Creating the USB erases the selected drive entirely. Make sure you pick the right one.
