I did not want to have it be a topic in the automotive microconf, as I believe there is enough material for a couple of hours on fastboot alone. It was not clear to me what topics might be in the boot and core os microconf, so I proposed fastboot as separate. Let's merge this then (the LPC guys want this to). We could copy the stuff from the fastboot MC wiki page into the boot/core OS wiki page, or the other way round. And preference? I'd still call this Boot and Core OS MC as this has the slightler broader topic, I guess...

Changing the CC list is a _very_ bad habit. Anyway, a few notes on UBI fastmap. Before we talk about optimizing it we have to make sure that it is stable. Currently it has not much users because embedded folks are a few kernel releases behind. I expect that we'll face some issues (hey it's software!). Instead of making the code more complicated we have to make very sure that it works well. Fastmap got much more complicated than I thought while developing the first proof of concept implementation. We also have to think more about userland support, e.g. making tools like ubinize fastmap aware... User want ready to use fastmap UBI images and not images which have to be converted by the kernel on the very first boot. Sharing UBI EBA table between U-Boot and the kernel would be a nice feature, but we also have to make sure that we can share the EBA table between two kernels (think of kexec). So, a more general solution is needed. -- Thanks, //richard ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
