Parallel deployments of Linux distributions.
Upgrade the systems in an atomic way.
Update the images with differential content (just the missing or modified blocks are downloaded).

For more information about how znx works, please refer to the documentation.

In the image below, you can see znx's boot menu.

To try it out, download the AppImage, give execution permissions to the AppImage, download a compatible ISO file and run znx as root.

Usage: znx <option | command>

Options:

  -v, --version                          Print the commit hash that generated this binary.

Commands:

  init <device>                           Initialize the storage device.
  restore <device>                        Restore the ESP (EFI System Partition) of the given device.
  deploy <device> <image> <URL | path>    Deploy an image on a storage device. Do not use whitespaces in filenames.
  update <device> <image>                 Update the specified image.
  revert <device> <image>                 Revert to the previous version of the image.
  clean <device> <image>                  Remove the backup that is created during an update.
  reset <device> <image>                  Delete all user data of the specified image.
  remove <device> <image>                 Remove the specified image.
  stats <device> <image>                  Show statistics about the provided image.
  list <device>                           List the deployed images.

Examples:

  Initialize a device:
  - znx init /dev/sdX

  Restore the ESP of a device:
  - znx restore /dev/sdX

  Deploy an image:
  - znx deploy /dev/sdX vendor/release http://foo.bar/image.iso
  - znx deploy /dev/sdX vendor/release /path/to/image.iso

  Update an image:
  - znx update /dev/sdX vendor/release

  Revert an update (downgrade):
  - znx revert /dev/sdX vendor/release

  Delete the backup of an image:
  - znx clean /dev/sdX vendor/release

  Reset an image to its original state:
  - znx reset /dev/sdX vendor/release

  Remove an image:
  - znx remove /dev/sdX vendor/release

  Show statistics about an image:
  - znx stats /dev/sdX vendor/release

  List the deployed images on a device:
  - znx list /dev/sdX

Be sure to replace /dev/sdX with the name of your device, use the commands lsblk, fdisk or blkid to find the correct device.

NOTE: If you are not so into typing commands in a terminal, you can check znx-gui, which is a Qt-based graphical frontend for znx, and is provided as an AppImage.
