Current situation

Kernel is build without tls module.

Impact

Applications and containers cannot offload TLS to the Kernel.

Ideal future situation

tls module is enabled or at least available.

Implementation options

Add CONFIG_TLS=y to https://github.com/flatcar/coreos-overlay/blob/main/sys-kernel/coreos-modules/files/commonconfig-5.15
