Off by default risks bit-rot for people not building it; it's generally best to default to off only if the feature requires dragging in extra libraries or similar build items not likely to be present in all development environments (and even then, auto-probing for required prerequisites is nicer than hard-coding off). Would on-by-default be a saner choice, or would that drag in too many extra dependencies for building? -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
