Description

Install Fedora CoreOS and tune a kernel parameter under /proc/sys as described in the documentation.

Setup

  1. Download and verify the latest FCOS next image (pick the right image for your environment).

How to test

  1. Create an Ignition file. When writing the configuration, change a value under /proc/sys by adding to /etc/sysctl.d/. The example alters the SysRq bits, but feel free to tune another parameter.
  2. Launch your Fedora CoreOS system using this Ignition file. See the Quickstart and the provisioning docs for a guide on how to launch FCOS in most environments (bare metal, virtual, cloud, etc).

Expected Results

  1. You can SSH successfully into your FCOS system.
  2. The parameter tuned via the ignition file can be seen under /proc/sys.
  3. The tuned parameter(s) persist through reboots.
  4. The linked documentation makes sense, nothing is obviously missing, and the instructions are clear.
