build: Add TARGET_ROOTFS_RESERVED_PCT option to reduce wasted space
The genext2fs tool will 'reserve' 5% of the image size by default, apparently by creating a huge lost+found directory. In fact it seemed to be much more than 5% in practice — I saw an image with 8MiB used, and recovered about 2MiB of it by deleting the 'empty' lost+found directory: /dev/loop0 48377 8482 37438 19% /mnt/spare # rmdir lost+found/ /dev/loop0 48377 6014 39906 14% /mnt/spare This makes it configurable, but leaves it at the genext2fs default of 5% for now. It should probably be changed to default to zero, but that can be a separate patch.
