My question was about "at runtime": my thinking was that it's useful to spell out to the user that they shouldn't expect the final released performance from the current system, perhaps adding a message somewhere in the UI, so that certain websites who shall remain nameless don't try to benchmark the debug builds. But I just had another variant of this idea: could the string "debug" be embedded in the release string of the kernel? (and wire this up in the specfile so that it's automatically added) so e.g. kernel-3.3.0-0.rc3.git6.2.fc18 would become: kernel-3.3.0-0.rc3.git6.2.debug.fc18 or kernel-3.3.0-0.rc3.git6.2.fc18.debug That way it'd show up everywhere e.g. in uname -a, in gnome-system-monitor, on logon, etc, and make it obvious that the debug code is enabled.
