It is possible to have Kernelcare ignore unknown kernels, such as newer kernels, to hide messages stating Kernelcare is not supported. The newer kernels would not yet have patches released, so support arrives once Kernelcare begins releasing those patches.
When checking to see if Kernelcare is compatible, the following output may be seen from the below command:
# wget -qq -O - https://kernelcare.com/checker | python
This script reaches out to https://patches.kernelcare.com to see if any patches exist. When none exist, such as for a newer CloudLinux Hybrid kernel, it will report "UNSUPPORTED".
To ignore these messages from Kernelcare, the below command can be executed as the root user:
echo "IGNORE_UNKNOWN_KERNEL=True" >> /etc/sysconfig/kcare/kcare.conf
