Currently they do not. It would require an updated interface to do so,
as sometimes instances can be used to continue tracing after a warning,
so I don't want to make it for all instances.

Perhaps we need an option for these too, and have all options be
updated via the command line. That way we don't need to make special
boot line parameters for this. If we move these to options (keeping the
proc interface for backward compatibility) it would make most features
available to all with one change.
