On the Raspberry Pi Fedora Remix I'm shrinking the image as much as possible by shortening the last (root) partition. The partition is resized to fill the SD card on first boot (fdisk, reboot, resize2fs). This results in a small image size, minimizes unnecessary writes to the SD card, works on any card size, and lets you take full advantage of the space on the card. Perhaps we should adopt that approach for the images? -Chris _______________________________________________ arm mailing list arm@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/arm
