from the department of opportunity-bearing-tradeoffs... For XO-1.5 we build our OS images to be a bit "short" of the stated SD card size, because different SD cards placed in mfg vary in exact size.
That means we always have a bit of space left over. We could add an init script that sets up a small swap partition right there. Technically it's not a big deal, it's reasonably fast (for first-boot). Needs to be combined with a low-swappiness sysctl setting (so as to avoid pointless SD Card wearout). The upside is that we'd have the Linux kernel able to use its VM as it wishes. We're pretty alone in trying to run a general purpose desktop distro without VM, and we sure pay the price for that currently. Downsides - XO-1 gets left alone in VM-lessness. - Increased SD card wear (should it matter? Our qualification process is stringent... so if it passed, we should get to use the damn card...) - Slightly longer first boot - Slightly more fragile first boot (can we make it failsafe?) - ??? cheers, m -- martin.langh...@gmail.com mar...@laptop.org -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
