No, that's what I'm saying. We cannot cache anything as any information may change at any time. The rule here is simple: if you want metadata, you have to be aware that they come at a price. If you don't need them, don't request them :) Thanks, Daniel _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
