Causes error and log messages emitted by Onload to be written to the system log rather than written to standard error. This includes the copyright banner emitted when an application creates a new Onload stack.

By default, Onload logs are written to the application standard error if and only if it is a TTY.

Enable this option when it is important not to change what the application writes to standard error.

Disable it to guarantee that log goes to standard error even if it is not a TTY.
