Always warn if something fails, and clarify that the involved utility functions do so in their name. Drop the REBOOT_PARAM_FILE macro. We don't do this for other flag file paths like this, so don't do this for this one either. The path isn't configurable anyway, hence let's make this easier to read by avoiding this one indirection.
