Description
Install Fedora CoreOS and tune a kernel parameter by sysctl as described in documentation.
Setup
- Download and verify the latest FCOS next image (pick the right image for your environment).
How to test
- Create an Ignition file. When writing the configuration, tune a kernel parameter by adding to it
/etc/sysctl.d/90-sysrq.conf. The documentation alters the bits for SysRq key but feel free to change another parameter. - Launch your Fedora CoreOS system using this Ignition file. See the Quickstart and the provisioning docs for a guide how to launch FCOS in most environments (bare metal, virtual, cloud, etc).
Expected Results
- You can SSH successfully into your FCOS system.
- The parameter(s) specified in the ignition file can be seen in
/proc/sysand the system behaviour is changed accordingly. - The changes in
/proc/syspersist through reboots. - The linked documentation makes sense, nothing is obviously missing, and the instructions are clear.
