WARNINGS:
- Use distro-packages where possible
If your distribution packages $kata_project, you should use these packages rather
than running this script.
- Packages will **not** be automatically updated
Since a package manager is not being used, it is **your** responsibility
to ensure these packages are kept up-to-date when new versions are released
to ensure you are using a version that includes the latest security and bug fixes.
- Potentially untested versions or version combinations
This script installs the *newest* versions of $kata_project
and $containerd_project from binary release packages. These versions may
not have been tested with your distribution version.

Usage: $script_name [options] [<kata-version> [<containerd-version>]]
Description: Install $kata_project [1] (and optionally $containerd_project [2])
from GitHub release binaries.
Options:
-c <flavour> : Specify containerd flavour ("lts" | "active" - default: "lts").
Find more details on LTS and Active versions of containerd on
https://containerd.io/releases/#support-horizon
-d : Enable debug for all components.
-D : Install Docker server and CLI tooling (takes priority over '-c').
-e : List short names and details for local hypervisor configuration files (for '-S').
-f : Force installation (use with care).
-h : Show this help statement.
-H <hypervisor> : Specify the hypervisor name to use when *INSTALLING* a system.
-k <version> : Specify Kata Containers version.
-K <tarball> : Specify local Kata Containers tarball to install (takes priority over '-k').
-l : List installed and available versions only, then exit (uses network).
-L : List short names and details for official packaged hypervisor configurations (for '-S').
-N : Install nerdctl (takes priority over '-c', only implemented for x86_64 and ARM).
-o : Only install Kata Containers.
-r : Don't cleanup on failure (retain files).
-S <hypervisor> : Only change the hypervisor config for an *EXISTING* installation.
-t : Disable self test (don't try to create a container after install).
-T : Only run self test (do not install anything).
Notes:
- The version strings must refer to official GitHub releases for each project.
If not specified or set to "", install the latest available version.
- The '-L' option requires an installed system.
> **Note:** For details of each hypervisor, see [3].
- If an invalid hypervisor name is specified with the '-H' option, an
error will be generated, but the system will be left in a working
state and configured to use the hypervisor configured at build time.
> **Note:** For details of each hypervisor, see [3].
- Since '-L' cannot be used until a system is installed, if you wish
to change the configured Kata hypervisor, unless you know the
hypervisor name, the recommended approach is to:
1) Install this script with no arguments to install a Kata system.
2) Run again with '-L' to list the available hypervisor configurations.
3) Run again with '-S <hypervisor>' to switch to your chosen hypervisor.

$warnings
Advice:
- You can check the latest version of Kata Containers by running
one of the following:
$ $script_name -l
$ kata-runtime check --only-list-releases
$ kata-ctl check only-list-releases
