 ## A toggle indicating if the kexec_load syscall has been disabled. This value defaults to 0 (false: kexec_load enabled), but can be set to 1 (true: kexec_load disabled). Once true, kexec can no longer be used, and the toggle cannot be set back to false. This allows a kexec image to be loaded before disabling the syscall, allowing a system to set up (and later use) an image without it being altered. Generally used together with the "modules_disabled" sysctl.
 ## Disables kexec which can be used to replace the running kernel.
 kernel.kexec_load_disabled=1

+## Why is this in a dedicated config file?
+## Package ram-wipe requires kexec. However, ram-wipe could not ship a config
+## file /etc/sysctl.d/40_ram-wipe.conf which sets 'kernel.kexec_load_disabled=0'.
+## This is because once systemd-sysctl.service has set 'kernel.kexec_load_disabled=1'
+## it cannot be undone without reboot. This is a upstream Linux security feature.
